Silicone Flanged Pull Plugs

Series: SFPP

Silicone flanged pull plugs for weld nut & first-thread masking (600°F)

Designed to keep the top or first thread clean during industrial finishing — when no powder, paint or anodizing is allowed. Eliminates rework by masking weld nuts and top threads in one step. 40-45 durometer Shore A silicone.

These indispensable masking plugs reduce costs by speeding up the process of masking 82° and 90° countersinks. To use, insert 'tail' into thru-hole, then pull plug into place with flange resting on opposite side for first thread protection.

Identify correct thread size before selection.

If oversized, lubricate with water or alcohol before insertion.
