Round Silicone UNJS Threads

Masking Pull plugs are ideal for masking threaded and plain through-holes. To apply just pull the thinner end of the plug through the hole until it stretches the larger end through the hole then release it so it will compress and make a tight seal. Use the Flanged Pull plugs to mask the backside of the hole. These come in a premium high temp silicone material or in an economical reduced temp EPDM material. Applications include Powder Coating, E-Coating, Plating and Anodizing.
