Frequently asked about Straight Connectors

Do nylon connectors need a locknut?

Yes. Each connector is supplied with its steel locknut and an O-ring; no separate gasket or flat washer is needed, and we do not offer a flat-washer version. The O-ring seats against the enclosure wall at the knockout and is compressed by tightening the locknut from inside. Hold the fitting still and turn the locknut — spinning the fitting drags the O-ring and is the usual cause of leaks.

Which body should I choose: straight, 45° or 90°?

Use straight where the conduit meets the enclosure square on; 45° and 90° where the conduit has to change direction immediately at the box to avoid a tight bend in the conduit itself.

Are the connectors rated for outdoor use?

Yes. They are cULus Listed for wet locations and UV-stabilised for permanent outdoor exposure.
