This component is used in the following industrial products
An aluminum cable gland is a mechanical device used to attach and secure the end of an electrical cable to equipment, providing strain relief and environmental sealing.
A mechanical fitting that creates a leak-tight seal by compressing a ferrule or sleeve onto a tube or pipe when tightened.
A mechanical device used to securely attach and seal the end of an electrical cable to equipment, providing strain relief and environmental protection.

Manufacturer profiles associated with Compression Nut.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Aluminum compression nuts are lighter, more corrosion-resistant in certain environments, and typically anodized for insulation. Brass nuts offer better conductivity and are preferred in explosive atmospheres. Material choice depends on application requirements like weight, corrosion resistance, and grounding needs.
Refer to manufacturer specifications based on nut size and cable diameter. Generally, apply 1/4 turn past hand-tight for metric threads, or use torque values from the specs table. Over-torquing can damage the sealing ring, while under-torquing compromises the IP rating.
Limited reuse is possible if threads and compression surfaces are undamaged. However, the sealing ring should always be replaced. Aluminum nuts are more prone to thread galling than brass or stainless steel versions.
