Sealing Lock Nuts

Sealing lock nuts secure threaded conduit and fittings to electrical boxes, panels and equipment enclosures while helping protect the entry point from moisture. Their integrated sealing element forms a barrier around the connection for dependable indoor and outdoor installations.

This collection features steel sealing locknuts with molded PVC seals. The threaded design provides firm attachment to compatible conduit fittings, while the integral gasket helps create a raintight, watertight and oil-resistant connection without requiring a separate sealing washer.

Sealing conduit locknuts support telecommunications, electrical, broadband, utility and industrial infrastructure. They are commonly used at junction boxes, cabinets, control panels, equipment shelters and other enclosures exposed to moisture or demanding environmental conditions.
