Your French distributor asks for a raccord étanche. Your Mexican integrator specifies a prensacables IP68. Your Brazilian panel shop writes prensa-cabo, and your German client insists on a Kabelverschraubung. All four want the same device — a waterproof cable gland — yet none of those words survives a straight translation into a purchase order.

That is the trap. Cable gland vocabulary is a trade language, not a standardised vocabulary. There is no international register of cable entry terms, so the part name is whatever the local electrical trade decided to call it. The thread size and the IP code, by contrast, are fixed international codes that mean exactly the same thing in Lyon, Monterrey, São Paulo and Yueqing. Translate one layer and you are being helpful. Translate all three and you will receive the wrong part.

This guide maps cable gland terminology across French, Spanish, Portuguese, German and Italian, separates the words that should be translated from the codes that must never be, and gives you a bilingual RFQ block you can paste into any email.

Why Cable Gland Terminology Breaks Down Across Languages

A cable gland is a mechanical cable entry device that anchors a cable, seals the entry point and, where required, bonds the armour or screen to the enclosure. That definition is stable. The name is not.

French uses presse-étoupe, literally “stuffing-box presser” — a term inherited from packed gland technology on pumps and valves. Spanish uses prensaestopas, “packing presser”, from the same engineering lineage. Portuguese uses prensa-cabo in Brazil and passa-cabos in Portugal. German uses Kabelverschraubung, “cable screw connection”. Italian uses pressacavo. English itself splits: the UK says cable gland, while the US says cord grip, cable strain relief, cable fitting or cable connector.

None of these is wrong. That is the problem. When a spec sheet is translated between them, the meaning drifts, and the drift lands on the factory as an ambiguous order.

The fix is to stop treating the whole specification as language-dependent. A cable gland specification has three layers, and only one of them changes language.

Once you separate those three layers, most multilingual confusion becomes mechanical rather than linguistic. You translate the label, you never translate the code, and you always state the numbers.

Cable Gland Terms in French, Spanish, Portuguese, German and Italian

The table below covers the vocabulary that appears most often in a real specification, an RFQ or an installation drawing. Use it as a working glossary rather than a dictionary: the terms in the same row describe the same physical function, not necessarily an identical product.

Three regional variations are worth memorising because they cause repeated confusion. Brazilian and European Portuguese diverge on several core terms, so a Portuguese-language drawing from Lisbon may not match the vocabulary your São Paulo customer uses. Latin American Spanish is broadly consistent, but Mexico and Argentina both borrow English words more freely than Spain does. And US English uses cord grip or strain relief where the UK uses cable gland, which matters when a North American client sends a Bill of Materials written against a UL-based specification.

A practical habit: when you write the product line in an email, write the English term first and the local term in brackets. Waterproof cable gland (presse-étoupe étanche) costs you four extra words and removes an entire class of misunderstanding.

False Friends and Machine-Translation Traps

The most expensive terminology errors in this trade come from machine translation, not from human misunderstanding. Machine translation engines are trained on general text, and gland in general French, Spanish and Portuguese text is an anatomical word, not an electrical one. Translating “cable gland” word by word produces results that range from confusing to embarrassing.

Two of these deserve extra attention. Raccord étanche is a category term, not a part name: a French buyer asking for a raccord étanche may want a cable gland, a conduit fitting or a hose connector, and the only way to know is to ask for the thread size and the cable diameter. And pasamuros is genuinely dangerous, because an unsealed wall bushing will pass a visual inspection and then leak on the first wet day.

Thread Designations Do Not Translate

Thread designations are the anchor of the whole specification, and they are the part buyers most often damage by translating. M20 × 1.5 is M20 × 1.5 in every language. PG11 is PG11. G 1/2″ is G 1/2″. NPT 1/2″ is NPT 1/2″.

What does change is the name of the thread family. If your customer writes filetage gaz and you read it as “gas thread” and convert it to a metric size, you will ship a gland that does not enter the panel.

One more trap sits inside this layer: fractional inch threads. A NPT 1/2″ gland is not a 12.7 mm gland, and it is not an M12 gland. Never convert a fractional inch thread designation into millimetres. The conversion is arithmetically correct and commercially wrong, because the converted number describes a thread that does not exist. If your customer’s drawing mixes both systems, that is a genuine question worth asking before the order is placed. The metric, PG and NPT conversion reference covers the family relationships in more detail.

IP Ratings Across Languages: The Code Stays, the Label Changes

The IP code is the second layer that must never be translated. IP68 is IP68. What changes is the name of the rating system, and that is where purchase orders go wrong, because a buyer may reasonably assume that étanche, estanco or wasserdicht is the same claim as IP68. It is not.

The adjectives in the middle rows are marketing language, not ratings. A gland described as étanche has made no measurable claim. Only the IP code does, and even the IP code needs one addition: IEC 60529 fixes the test conditions for IP67 at 1 metre for 30 minutes, but leaves the depth and duration for IP68 to the manufacturer. Two glands can both be IP68 while one is tested at 1.5 metres for 30 minutes and the other at 10 metres for 72 hours. The IP68 rating explained walks through what the code does and does not prove.

For that reason, the correct line on a multilingual purchase order is never just “IP68”. It is: IP68 to IEC 60529, tested at [depth] for [duration], on the fully assembled gland. Numbers survive translation. Adjectives do not.

North American projects add a second system. NEMA 250 enclosure types appear on US and Canadian specifications alongside IP codes, and the two are not interchangeable. IP66 is often presented as equivalent to NEMA 4 or 4X, but NEMA ratings also address corrosion resistance, icing and construction details that the IP scale ignores. If a specification calls for NEMA 4X and your gland only carries an IP test report, the inspector may reject it regardless of how the two are marketed.

Cable Outer Diameter: Where Decimal Commas Cause Real Failures

There is one more numerical trap, and it lives in the cable outer diameter. Most of continental Europe, Latin America and Brazil write decimals with a comma. English-language drawings write them with a point. A clamping range written as 6,5 – 12 mm can be read as two separate figures by a reader expecting a point, and a range written as 6.5 – 12 mm can be read as a single malformed number by a reader expecting a comma.

Thousands separators create the mirror problem. A quantity of 1,000 pieces in English is 1.000 pieces in French, Spanish, Portuguese, German and Italian. Misread one way, an order of one thousand looks like an order of one.

The fix is mechanical. Write every dimension with an explicit unit and never rely on the separator alone:

• Cable outer diameter: 6.5 mm – 12 mm (6,5 mm – 12 mm)
• Thread length: 10 mm
• Torque: 3.5 N·m (3,5 N·m)
• Temperature range: −40 °C to +100 °C
• Quantity: 1,000 pcs (1.000 Stück)

If the cable diameter is the part of the specification you are least sure about, measure it rather than trusting the cable datasheet. A cable marked 10 mm² is not a 10 mm cable. The method for measuring cable outer diameter against a sealing range is worth checking before the order is confirmed, because the sealing range is the single most common reason a correctly rated gland still leaks.

Materials and Finishes: What Changes and What Stays

Material names sit in an awkward middle layer. They translate, but they translate into words that carry slightly different technical weight, so the safest habit is to write the material both in words and in its standard designation.

Stainless steel is the clearest example. French says inox, Spanish says acero inoxidable, Portuguese says aço inoxidável, German says Edelstahl and Italian says acciaio inossidabile. But the grade designations you should actually order by are the material codes: 304 and 316, or their EN equivalents A2 and A3. A standard stainless steel cable gland built from 304 or 316 with a PA claw and an NBR seal reaches IP68 and holds its sealing force in coastal, marine and chemical environments, which is why the grade matters more than the adjective.

Brass behaves the same way. French laiton, Spanish latón, Portuguese latão, German Messing, Italian ottone — five words for one material. A nickel-plated brass cable gland is the usual default for general industrial panels, and the plating is worth specifying in words because nickelé, niquelado and vernickelt all describe the same finish.

Nylon is where the vocabulary diverges most. English says nylon, Spanish often says nailon, Spanish and Portuguese engineering drawings say poliamida, German says Polyamid, Italian says poliammide, and French says polyamide. All of them mean PA66 in practice. A standard nylon cable gland in PA66 with an NBR seal is the lightest and most economical option for general outdoor and enclosure work, and it is the product most often ordered under a translated name that omits the material entirely.

Elastomer abbreviations are the one group that genuinely does not translate. NBR, EPDM and silicone are written the same way on every drawing, and they should stay that way. Write “NBR” and not its local-language expansion, because the abbreviation is the specification.

Standards and Certificate Names Across Markets

Standards have a national prefix and an international body. The cable gland product standard is IEC 62444, adopted in Europe as EN 62444. Each country republishes the identical EN text under its own prefix: NF EN in France, UNE-EN in Spain, NP EN in Portugal, DIN EN in Germany and BS EN in the United Kingdom. The technical content is the same document, so a supplier quoting any one of those prefixes is quoting the same requirements — but a buyer who does not recognise the local prefix may think a certificate is missing when it is not.

One naming habit causes genuine problems. EN 50262 was the older European cable gland standard, and it has been withdrawn and replaced by EN 62444. Suppliers who still quote EN 50262 are quoting a superseded document. That is not necessarily dishonesty, but it does mean the technical file may not have been updated. The IEC 62444 and EN 50262 standard guide explains how to read that situation and what to ask for.

Certificate names themselves do not translate. CE marking, the EU Declaration of Conformity, RoHS and REACH are written identically in every EU language. Installation requirements, by contrast, are national: Brazil works to ABNT NBR 5410 for low-voltage installations, and North American projects reference the NEC alongside NEMA enclosure types. A gland that satisfies the product standard can still fail an installation inspection if the national wiring rules were never checked.

A Bilingual RFQ Block You Can Paste Into Any Email

The most reliable defence against multilingual drift is a specification block that states the same thing in two languages and never translates the codes. The block below is ten lines long and fits in any email.

Line 10 is the one buyers skip and later regret. When the only drawing in circulation is a translated one, every subsequent question is asked against a document that may have lost a decimal comma or a thread suffix somewhere in the conversion.

How to Verify a Supplier When English Is Not Your First Language

Verification is where multilingual sourcing either holds together or falls apart. Six checks cover the failure modes that terminology problems create.

Note what these checks have in common. None of them depends on vocabulary. They all depend on a code, a number or a physical measurement — the parts of a cable gland specification that mean the same thing in every language your customers speak.

Conclusion

Multilingual cable gland sourcing goes wrong when the whole specification is treated as translatable. It goes right when you separate the three layers: translate the product name so both sides understand each other, never translate the thread designation or the IP code, and always state the numbers with explicit units.

Keep the glossary above next to your quotation templates, add the ten-line RFQ block to your standard enquiry email, and the next raccord étanche or prensacables IP68 you receive will resolve into a clean specification in a single reply instead of three. If you are working through a specification now and want the thread, material and IP details confirmed against a real product, send the requirement to our engineering team and we will check it line by line.

FAQ

What is a cable gland called in French?

The standard French term is presse-étoupe. The phrase raccord étanche is broader and covers any watertight connection, including hose and conduit fittings, so it is not a precise equivalent. Avoid the word gland, which is an anatomical term in French.

Is prensacables the same as prensaestopas?

Yes. In Spanish both words describe a cable gland, and both appear on commercial and technical documents. Pasamuros is a different part: it is a wall bushing or pass-through and may contain no sealing element at all.

What is the Portuguese word for cable gland?

Brazilian Portuguese uses prensa-cabo, and European Portuguese commonly uses passa-cabos. Machine translation frequently produces glande de cabo, which has no technical meaning and should never appear on a purchase order.

Do thread sizes change in other languages?

No. M20 × 1.5, PG11, G 1/2″ and NPT 1/2″ are written identically in every language. Only the name of the thread family changes, such as filetage métrique in French or rosca métrica in Spanish and Portuguese. Never convert a fractional inch thread into millimetres.

How do you say IP68 in Spanish, French or German?

The code stays as IP68. Only the name of the rating system changes: grado de protección IP in Spanish, indice de protection in French, grau de proteção in Portuguese and Schutzart in German. Words such as estanco, étanche or wasserdicht are descriptive adjectives, not ratings, and should never replace the IP code.

Does IP68 mean the same thing in every country?

The code means the same thing, but the test conditions do not. IEC 60529 fixes IP67 at 1 metre for 30 minutes, while for IP68 the depth and duration are set by each manufacturer. Two glands can both be IP68 with very different immersion performance, so the test depth and duration must always be stated on the order.
