Pipe Thread Protectors

Pipe thread protectors are one of the most common applications for StockCap's line of protective caps and plugs. As such, there are many different options depending on the application and functionality required.

Round Vinyl Caps

Vinyl caps are excellent for use as pipe thread protectors. The flexible vinyl material stretches over the threads to provide a tight seal that not only protects the threads, but also keeps contaminants out of the pipe or tubing. The pliable vinyl cushions the threads against damage and will not crack or shred like many hard plastic caps. Vinyl caps are available in both short and long versions.

Vinyl Tab Caps

These caps offer the same advantages of the round vinyl caps with the added benefit of having EZ removal tabs.
