The Schedule 40 PVC Threaded Plug is the professional solution for terminating any female pipe threaded connection in your system. Whether you are capping off an unused port on a manifold, closing the end of a threaded tee, or temporarily sealing a line for pressure testing, this plug ensures a leak-proof closure. It is one of our most essential irrigation fittings for maintaining a flexible and adaptable water layout.
Molded from durable Schedule 40 PVC, this plug features standard Male Pipe Threads (MPT) and a hexagonal head for easy tightening with a wrench. Unlike slip caps that require glue, this threaded plug allows for future system expansion—simply unscrew it when you are ready to add a new zone or component.

Follow these steps for a leak-free seal.
Step 1: Clean Threads
Ensure the female threads of the fitting you are plugging are clean and free of debris or old tape.
Step 2: Apply Tape
Wrap the male threads of the plug with 3-5 layers of thread seal tape. Wrap in a clockwise direction (looking at the bottom of the plug) to prevent unraveling.
Step 3: Hand Tighten
Screw the plug into the fitting by hand until it is snug. Be careful not to cross-thread.
Step 4: Final Tightening
Use a wrench or pliers on the hex head to tighten the plug one additional half-turn. Do not overtighten, as this can crack the female fitting.
