Conduit Hole Seal 1.37 in

This stainless-steel seal closes unused pushbutton or conduit openings in electrical enclosures. It fits a 1.37 in diameter hole and matches 1 in conduit sizing. The part is designed for panel builders and maintenance crews who need a clean, code-compliant closure.

304 Stainless Steel Material

The seal is made from 304 stainless steel for corrosion resistance in indoor and outdoor environments. This alloy withstands moisture, chemicals and temperature swings better than plated steel or plastic alternatives. Specifiers choose it when the installation demands long-term durability.
