3-1/2 & 4 NEOP ELECTRICAL CONDUIT GASKET

Panel builders know that a rated enclosure is only as good as its seals, and the conduit knockout is one of the first places that rating gets tested. This 3-1/2 in. and 4 in. neoprene electrical conduit gasket is sized to fit standard 3-1/2 in. and 4 in. trade-size conduit fittings and knockouts.

Neoprene's resistance to ozone and weathering makes it a solid choice anywhere the panel might see washdown, humidity, or an outdoor-adjacent installation. It's a standard component in control panel and switchgear assembly, closing the gap at the conduit fitting so the enclosure holds its rated protection.
