Silicone Rubber Caps and Plugs: High Temperature Heat Resistant
Powder coating painting masking and thread/fitting protection
500F / 260C continuous rating with weld splatter / molten metal splash protection.
Our high temperatures silicone rubber caps and plugs are manufactured to exacting standards from our formulation of high-temperature silicone rubber. 

Commonly used to mask to protect bolt and screw threads in powder coating painting and coating operations, and due to the high temperature rating, can often be reused multiple times.

Due to the non-stick characteristics of silicone rubber, molten metal, weld splatter and grinding sparks do not stick to the silicone tubing, silicone caps or silicone plugs.

We stock large quantities of most sizes.
