Introduction

Choosing between an IP68 nylon cable gland and a brass cable gland is one of the most common decisions in industrial and outdoor electrical installations.
Both options provide waterproof protection, but they differ in strength, cost, and application suitability.

This guide compares the two to help engineers and purchasing managers make the right choice.

Material and Mechanical Strength

Nylon Cable Gland

• Made from PA nylon
• Lightweight
• Suitable for standard industrial environments

Brass Cable Gland

• Made from nickel-plated brass
• Higher mechanical strength
• More resistant to vibration and impact

👉 For heavy-duty machinery, brass cable glands are usually preferred.

Waterproof Performance (IP68)

Both nylon and brass cable glands can achieve IP68 waterproof protection when properly installed.

The sealing performance depends on:

• Compression design
• Quality of sealing ring
• Correct installation

👉 In terms of waterproof rating alone, both are equally reliable.

Cost Consideration

Nylon cable glands are generally more cost-effective, especially for bulk orders.

Brass cable glands have higher material and machining costs but offer longer durability in demanding conditions.

Conclusion

Choose nylon for lightweight, cost-effective installations.
Choose brass for strength, durability, and vibration resistance.
