Engineered for durability, this grey cable gland ensures that cables are held firmly in place while maintaining the integrity of the enclosure. With its robust construction, it serves as an essential element for professional cable management in both industrial and commercial environments.

Advantages

This cable gland offers exceptional protection against environmental factors, featuring an IP68 ingress protection rating that guarantees complete resistance to dust and protection against water immersion. The use of high-grade polyamide material ensures long-term resistance to mechanical stress and chemical exposure. Its design facilitates quick and straightforward installation, reducing assembly time while maintaining a high standard of safety and reliability for electrical connections.

Suitable for

• Securing cable entries in electrical distribution boxes
• Industrial automation and control panels
• Outdoor electrical installations requiring moisture protection
• Commercial building electrical systems

When it may not be suitable

This cable gland is designed for standard polyamide applications and may not be suitable for environments involving extreme heat or direct exposure to harsh corrosive chemicals that degrade plastic materials. It is also not intended for use in high-pressure steam cleaning environments or applications requiring metallic shielding for electromagnetic interference.

Key specifications

• Thread size: PG21
• Material: Polyamide
• Ingress protection rating: IP68
• Color: Grey
• Application: Cable strain relief and sealing

How to use

To install the cable gland, insert the threaded body through the pre-drilled hole in the enclosure wall and secure it firmly using the included locknut. Once the body is fixed, pass the cable through the gland. Tighten the dome nut to compress the internal sealing ring around the cable jacket, which creates a watertight and dustproof seal. Ensure the cable diameter matches the gland's clamping range for optimal performance.

What to consider before purchase

• Verify that the PG21 thread size matches your enclosure's mounting hole
• Check the cable diameter to ensure it falls within the clamping range of the PG21 gland
• Confirm the environmental conditions of the installation site

Usage recommendations

For maximum reliability, ensure the dome nut is tightened sufficiently to create a firm seal, but avoid overtightening, which could damage the plastic threads. Regularly inspect the gland during routine maintenance to ensure the seal remains intact and the cable is properly secured.
