Pipe Caps & Plugs

At StockCap, you'll find everything from plastic plugs for NPT threaded pipes to large diameter vinyl flange covers. Here are some of our more popular pipe caps and plugs.


Standard Vinyl Pipe End Caps and Pipe End Plugs

The major benefit to using vinyl caps and plugs for protecting pipe threads is the flexible vinyl material. It stretches to fit over threads and provides a tight seal against contamination while still being simple to install. And, unlike the harder plastic caps, vinyl will not crack, shred, or split.

Threaded Pipe Caps and Threaded Plugs

Threaded pipe caps and plugs are ideal for applications where fear of displacement due to internal air pressure exists. The pipe caps are available to fit the most popular ASAE thread sizes while the pipe plugs fit on common JIC fittings.
