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.
