The IP rating system helps engineers select the right protection level for electrical components. Among these ratings, IP68 is considered one of the highest levels for cable glands.
Understanding the IP Rating System
IP stands for Ingress Protection
The first digit indicates dust protection
The second digit indicates water protection
IP68 offers complete dust protection and long-term water resistance.
How IP68 Cable Glands Achieve Waterproofing
IP68 cable glands use:
Precision-designed sealing rings
Compression structures that adapt to cable diameter
Durable materials such as nylon, brass, or stainless steel
Proper installation is essential to achieve the rated protection level.
IP68 Nylon vs IP68 Brass Cable Glands
Nylon: Lightweight, insulating, cost-effective
Brass: Stronger, more resistant to vibration
Both can meet IP68 requirements when installed correctly.
