Quick Specs • Multiple sizes for use with Heyco-Flex Conduit and Tubing. See pages 1-1 and 1-2. • Smooth internal surfaces for easier wire installation around corner angles. • Resists salt water, weak acids, gasoline, alcohol, oil, grease, and 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 into an NPT 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 during assembly and can be easily removed by pulling while turning in a clockwise direction. • Suitable for indoor/outdoor use; for original equipment manufacturers or field installers. • Lower installed cost. • Black connectors up to 1½ provided with nylon locknut, packed separately. Larger than 1½ provided with O-ring and metal locknut. • Gray connectors provided with assembled O-ring and metal locknut. • Use of a sealing washer may be required for wet locations. See page 1-13. • See page 1-11 and 1-12 for locknuts.
