• PVC molded gasket: Creates a weatherproof, watertight, and oil tight seal ideal for wet locations and protecting electrical connections.
• UL Listed: Meets industry standard safety expectations for conduit fittings in commercial and residential installations.
• Designed for conduit: Intended specifically for use with Rigid Conduit, IMC, and threaded conduit connectors to secure connections to junction boxes.

Who It's For

This product is best for professional electricians, contractors, and serious DIYers working on outdoor or wet-location conduit installations who need a dependable, weatherproof locking solution. It is particularly well suited to projects using 1 1/2 in conduit connector fittings where a gasketed locknut is required to maintain a sealed enclosure.

Those who should look elsewhere are users needing nonmetallic or specialized stainless steel locknuts for highly corrosive marine environments, or people requiring a different size than 1 1/2 in, since this pack is specific to that conduit size.
