Component Specifications

Definition
A conduit gland, also known as a bushing, is a mechanical fitting designed to provide a secure, sealed entry point for electrical cables into conduit systems. It prevents the ingress of dust, moisture, and other contaminants while offering strain relief and grounding continuity in industrial wire harness installations. These components ensure electrical safety and system integrity in harsh environments.
Working Principle
The conduit gland works by compressing a sealing element (such as a rubber gasket or neoprene seal) around the cable when the gland nut is tightened. This creates a watertight and dustproof seal while mechanically securing the cable to prevent pull-out. The metallic body provides grounding continuity between the cable armor (if present) and the conduit system.
Materials
Body: Brass, stainless steel (AISI 304/316), galvanized steel, or nylon. Sealing elements: Neoprene, nitrile rubber (NBR), silicone, or EPDM. Locknuts and washers: Typically matching the body material.
Technical Parameters
  • IP Rating IP68 (common for industrial applications)
  • Cable Range 3mm to 40mm diameter
  • Thread Size M16 to M63 metric or NPT 1/2" to 2"
  • Certifications ATEX, IECEx for hazardous areas
  • Voltage Rating Up to 1000V AC/DC
  • Temperature Range -40°C to +100°C (varies by material)
Standards
ISO 9001, IEC 60079, UL 514B, DIN EN 62444

Frequently Asked Questions

What is the difference between a conduit gland and a bushing?

While often used interchangeably, a gland typically provides sealing and strain relief, while a bushing primarily prevents cable abrasion at conduit entry points. Many modern products combine both functions.

How do I select the right conduit gland for my application?

Consider cable diameter, environmental conditions (IP rating), material compatibility, thread type, and any required certifications (like ATEX for hazardous areas). Always follow manufacturer specifications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
