What this product is for
This 1-1/2 in sealing locknut is used to secure threaded conduit fittings, rigid conduit, or IMC to an enclosure while adding a sealing interface for liquid-tight applications. It is suited to trade installations where a standard locknut is not enough for the enclosure entry detail.
Use for
Use for 1-1/2 in trade size threaded entries, panel and enclosure terminations, and liquid-tight conduit connections where a sealing locknut is specified. Typical applications include rigid conduit and IMC terminations in commercial and industrial work.
Avoid for
Avoid using this as a substitute for a standard locknut where no sealing function is required, or on mismatched thread types and sizes. Do not assume liquid-tight performance unless the full fitting, enclosure, and installation method are suitable for the application and local code.
Best for
Best for electricians needing a steel locknut with sealing function for 1-1/2 in conduit entries. It is a practical choice when terminating threaded fittings to cabinets, pull boxes, or other enclosures in areas exposed to moisture.
Installed in
Installed in electrical enclosures, cabinets, junction boxes, pull boxes, and control panels with 1-1/2 in threaded conduit or fitting entries. Size reference: 1-1/2 in trade size is approximately 41 mm.
Why this product exists
This product exists to lock threaded conduit components to an enclosure while helping create a tighter sealed connection than a standard locknut alone. For buyers comparing options, the key decision point is whether the installation needs sealing performance in addition to mechanical retention.
Compared with similar products
Compared with a standard steel locknut, a sealing locknut is intended for applications where moisture resistance matters. Compared with non-metallic options, this steel version is typically selected where metal raceway systems and threaded rigid or IMC fittings are already being used.
