Non-metallic liquid-tight connectors terminate LFNC-B conduit into boxes, enclosures and equipment with a watertight, corrosion-free joint. Multi-piece Sealproof connectors are molded in nylon 6 with an O-ring and gland nut; the one-piece screw-on connectors are UV-rated PVC — in straight, 45° and 90° bodies from 3/8" to 2".
They are the right choice around pools, coastal sites and chemical exposure where a metal fitting would corrode. cULus Listed for wet locations to UL 514B; pair with Sealproof LFNC-B for a listed system.

Frequently asked about Non-Metallic Liquid Tight 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.
