Heyco-Flex™ Liquid Tight Conduit Fittings

Heyco Heyco-Flex™ Liquid Tight Conduit Fittings are designed for use with flexible, non-metallic Liquid Tight Heyco-Flex I Conduit and Heyco-Flex II Tubing. No disassembly of these Heyco conduit fittings is required. The installer can push the conduit or tubing onto the ferrule, then tighten the domed sealing nut. The completed assembly can be secured in the panel using the locknut or into an NPT threaded hole. A convex ferrule ensures a liquid-tight seal. No threading of the conduit is needed for assembly, eliminating the risk of cutting the conduit and creating leak paths. The complex conduit/connector system is reusable, and the fittings are offered in multiple sizes. Heyco-Flex Liquid Tight Conduit Fittings are suitable for indoor/outdoor use by original equipment manufacturers or field installers.
