Threaded sleeve

Threaded sleeves, also known as cable glands, cord grips, or conduit fittings, are mechanical devices designed to secure and protect the termination of electrical cables or wires as they enter enclosures, junction boxes, or equipment. These components provide strain relief, sealing against dust and moisture (IP ratings up to IP68), and ensure electrical continuity for grounding or bonding. They are available in various materials such as brass, nickel-plated brass, stainless steel, and plastic (nylon or polyamide), with thread types including metric (M), PG, NPT, and G (BSP). Key technical parameters include thread size, clamping range (cable diameter), and ingress protection level. Threaded sleeves are essential for maintaining the integrity of electrical installations in industrial, commercial, and hazardous environments.

These components are widely used in control panels, distribution boards, automation systems, motor connection boxes, lighting fixtures, and field instrumentation. They are critical in sectors such as manufacturing, energy, oil and gas, water treatment, and building services, where cable entry points must be sealed against environmental factors like water, dust, and vibration. In hazardous areas (ATEX/IECEx), certified threaded sleeves ensure explosion-proof installations. They also play a role in cable management for renewable energy systems, including solar inverters and wind turbines, as well as in data centers and telecommunications infrastructure.

Key subcategories include standard cable glands, EMC glands for electromagnetic compatibility, angled or 45-degree glands, and reducing glands for adapting thread sizes. Common article codes often follow patterns like M20x1.5, M25x1.5, PG11, PG16, or NPT 1/2, indicating thread type and size. For example, a brass nickel-plated cable gland with an M20 thread and a clamping range of 6-12 mm is a typical stock item. Other variants include armored cable glands for steel wire armored (SWA) cables, and hygienic glands for food and beverage applications. Accessories like lock nuts, sealing washers, and blind plugs are also available to complete installations.
