  • Heyco® Break-Thru™ Skinned-Over glands offer the flexibility to use fewer of
    the available holes while still providing a liquid tight seal around the conductors. Consult Heyco for additional Skinned-Over gland number, size, and hub configurations.
  • Heyco® Multi-hole glands provide the widest range of conductor through-hole size and number configurations, many of which are agency approved. See the tabular charts for specific approvals for specific parts. These approvals are not "global" or implied approvals; they are both real and part specific.
  • Integral Sealing Ring ensures a superior seal at the clearance or threaded mounting hole locaton, every time.
  • IP 68 rated.
  • Approved for NEMA 4, 4X, 6 and 6P applications.
  • Cordgrips are made of nylon construction with TPE sealing glands that resist salt water, weak acids, gasoline, alcohol, oil, grease, and common solvents.
  • For body part dimensions see NPT Cordgrips.
  • Multi-hole glands are only to be used with Heyco Liquid Tight Cordgrips and are not sold separately.
  • Consult Heyco for Cordgrips molded in other colors.
