High-Temperature Pull-Through Round Plugs

Good for electroplating, paint baking, and powder-coating applications, these plugs withstand temperatures up to 600° F for 15 minutes. To form a tight seal, use the smaller end of the plug to pull the larger end into a through hole.

Flanged Pull-Through Round Plugs

Designed with a flange, these plugs protect countersunk holes during anodizing, electroplating, paint baking, and powder-coating applications. All withstand temperatures up to 600° F. Use the smaller end of the plug to pull the larger end into a through hole to form a tight seal.

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.
