Multiple sizes for use with Heyco-Flex™ conduit and tubing.
All nylon construction resists salt water, weak acids, gasoline, alcohol, oil, grease and other common solvents. This feature is not assessed by UL certification and testing.
No disassembly required. Instead, the installer simply pushes the conduit or tubing onto the ferrule, then tightens the domed sealing nut. This completed assembly can then be secured in the panel by the locknut (or first secure the connector into a threaded hole).
No threading of the conduit or tubing is required to install. This eliminates the possibility of cutting the conduit and creating leak paths.
Complete conduit/connector system is reusable. Conduit will not wind tight onto the connector and can be easily removed without cutting and without damaging the connector.
Use of a sealing washer may be required for wet locations.
Suitable for indoor/outdoor use; for original equipment manufacturers or field installers.
Hardware:
- Black connectors up to 1" are provided with a nylon locknut; packed separately
- Gray Connectors and Black connectors (larger than 1") are provided with an o-ring and a metal locknut as one assembled unit

For use with Heyco-Flex™ Fittings.
Liquid tight, dust tight and oil tight at enclosure.
Suitable for wet locations requiring a separate gasket between the box and fitting due to imperfections in the box.
Also suitable for other panel or panel sealing applications.
Easy to install since washers seal off on the perimeter, not on the connector threads.
Special double sealing ridges compensate for minor unevenness at enclosure.
