Gland Nut Component – Electrical Equipment Manufacturing

Component Specifications

Definition

A gland nut is a critical component in cable gland assemblies, designed to compress the sealing ring or gasket against the cable and housing to create a secure, watertight, and dustproof seal. It ensures mechanical retention and environmental protection for electrical cables entering enclosures.

Working Principle

The gland nut works by threading onto the gland body, applying axial pressure to compress a sealing element (like a rubber gasket or neoprene ring) around the cable. This compression creates a radial seal that prevents ingress of liquids, dust, and gases while providing strain relief.

Materials

Typically made from brass, stainless steel (AISI 304/316), aluminum, or nylon/plastic for corrosion resistance and durability. Material choice depends on environmental conditions (e.g., marine, chemical, outdoor).

Technical Parameters

IP Rating IP68
Thread Size M16 to M63 metric or NPT threads
Temperature Range -40°C to +100°C
Torque Specification 10-50 Nm depending on size

Standards

ISO 9001, IEC 62444, DIN EN 50262

Frequently Asked Questions

What is the purpose of a gland nut in a cable gland?

It compresses the sealing ring to create an environmental seal and secure the cable mechanically.

Can gland nuts be reused?

Yes, if undamaged, but sealing rings often need replacement to maintain integrity.

How do I choose the right gland nut material?

Select based on environment: stainless steel for corrosive areas, brass for general use, plastic for non-metallic applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
