This is an IP68 Cable Gland, typically made from nickel-plated brass and designed for use with unarmoured cables. It provides a high degree of ingress protection (IP68), making it ideal for harsh, wet, or dusty environments. The gland ensures a watertight and dustproof seal around the cable, offering excellent strain relief and mechanical retention. Commonly used in outdoor electrical enclosures, automation systems, and marine or industrial applications where moisture and environmental protection are critical.
