Reducing Washer 1-1/2 in x 1 in Steel

This reducing washer connects conduit fittings of different diameters in electrical installations. It is intended for electricians and maintenance staff who need to step down from a 1-1/2 inch opening to a 1 inch connection. The steel construction provides mechanical strength for industrial and commercial environments.

Simple threaded installation with common tools

The washer fits between the conduit body and the locknut to create the reduction. No special tooling is required beyond standard wrenches used for conduit work. The most frequent issue is cross-threading when the washer is not seated squarely against the fitting face before tightening.

Verify conduit sizes and thread type before ordering

Confirm that the existing conduit hubs match the 1-1/2 inch and 1 inch trade sizes stated for this washer. Check that the thread standard on both sides is compatible with the fitting bodies being joined. Ensure the steel material is suitable for the environmental conditions of the installation site.
