  • For use with most electrical fittings.
  • 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 or chassis 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.
  • Molded of Santoprene 251-80; flammability classification 94V-0.
