These Heyco NPT hubs are ideal for flexible non-metallic liquid-tight conduits and tubings with a straight-through design. Their convenience comes from the fact that they do not need to be disassembled. The installer connects the conduit/tubing to the ferrule by a push-on connection that it then secures by tightening the domed sealing nut. The conduit will not wind tight, making it easy to pull off by twisting it clockwise.

Multiple sizes are available, with IP68 protection at a water pressure of up to 70psi (5bar). They are designed for indoor or outdoor use, by OEM or field installers. Once assembled, it can be fitted to the panel via the locknut or by connecting through an NPT threaded hole. The assembly is also reusable. The liquid tightness comes from the convex ferrule design which eliminates the need for conduit/tubing threading. It also means leak paths are not created by cutting the conduit.
