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.
