Heyco Straight-Thru Nylon Conduit Fittings

Heyco Straight-Thru Nylon Conduit Fittings are designed for flexible corrugated Nylon conduit and tubing. These Heyco Nylon conduit fittings require no disassembly. Instead, the installer pushes the conduit or tubing into the fitting, then tightens the domed sealing nut. These Straight-Thru fittings feature a silicone sealing gland to ensure a liquid-tight seal. No threading of the conduit or tubing is needed to install the fittings, eliminating the risk of cutting the conduit and creating leak paths.
