Heyco® Sealing Washers


  • Make fittings and connectors liquid tight, dust tight, and oil tight at enclosure.
  • Suitable for wet locations requiring a separate gasket between the box and fitting.
  • Also suitable for other 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.
