Caplugs has developed Pipe Thread Mask (PTM) series of masking cap plugs to protect threads on piping and tubing. These cap plugs prevent coatings that are applied during the pipe fabrication and secondary coating processes from getting inside of the pipe. Properly masking the delicate internal pipe threads is an important step during fabrication and coating.

Designed with a unique tear-away venting nipple, the cap plug allows for pressure release during the curing process and will stay watertight if the venting nipple is not removed. Additional design features include an outer rib enabling extra hold against the internal threading and an ergonomic handle for easy removal. The Ultrabake silicone material can withstand temperatures as high as 600°F.
