1/2" pipe cap bushings or pennies are used inside insulating bushings to cap off 1/2” EMT, rigid and IMC conduits that are not in use. Garvin Industries’ bushing pennies prevent dust, dirt, rocks and debris from falling in the conduit and clogging the pipe. They save and protect conduits making them suitable for later use. They can later be used with pull line and other pre-inserted wire pulling aids. They are also zinc electroplated for excellent corrosion protection.
