Cable Glands: Which type of cable gland should I use?

Cable glands are used to secure your wires and protect your application from environmental hazards and physical damage. They play a key role to ensure the safety, integrity and longevity of your electrical systems. But with various materials available, selecting the right cable gland can be a bit overwhelming. Let's discuss the key differences between Nylon and Brass cable glands!

Nylon Cable Glands

Nylon cable glands (NPT, PG & Metric) offer a cost-effective solution for indoor applications where environmental conditions are relatively mild/controlled. They provide excellent protection against moisture and dust, making them suitable for commercial, residential, and some industrial settings. Key benefits of nylon cable glands include:

Cost Effective: option for budget-conscious projects

Lightweight: Ideal for applications where weight is a consideration

Good moisture and dust resistance: Provides protection in controlled environments

When durability is important, nickel plated brass may be the solution for you. Brass cable glands  are best for harsher environments - meaning: high temperatures, vibration, shock and where electrical conductivity or electromagnetic shielding is necessary. Nickel plating not only gives a polished silver finish on the cable gland, but it serves as a protective layer to protect the much denser and stronger brass underneath. Without the protective finish, the cable gland would corrode quicker and turn color. Their superior strength, durability, and electrical conductivity make them indispensable for industrial, marine, and outdoor applications. Additional advantages of brass cable glands include:

Exceptional durability: Resists wear, tear, and harsh conditions.

Excellent electrical conductivity: Ensures optimal signal transmission.

Electromagnetic shielding: Protects against electromagnetic interference.

Corrosion resistance: Nickel plating enhances resistance to rust and corrosion.

In Summary

Always consider the specific requirements of your application, including environmental factors, cable type, and installation conditions, when selecting the appropriate cable gland material.
