Hollow High-Temperature Tapered Plugs
The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters. Good for electroplating, paint baking, and powder-coating applications, these plugs withstand temperatures up to 450° F for 20 minutes. Use the flange to remove them with ease.

Miniature Pull-Through Round Plugs
Also known as mouse tails, these tiny plugs fit through-hole IDs as small as 0.022”, 0.025", or 0.03”. They're commonly used for masking parts during finishing applications. Use the end of the plug to pull it into a through hole to form a tight seal.
Silicone plugs withstand higher temperatures than EPDM plugs.
EPDM plugs have excellent chemical resistance.
