Hayward PLUG WINTER 3" THRD W/SHRADER

The Hayward Winter Plug 3" Threaded with Schrader valve is built for winterizing large‑diameter plumbing lines that use 3" threaded fittings, offering both a secure mechanical seal and the ability to apply or monitor air pressure through the integrated Schrader valve. Its oversized expansion‑style rubber body creates a strong, reliable seal when tightened, helping keep water out of the line during freezing conditions and allowing technicians to pressure‑test the system for leaks. The threaded design ensures a stable fit in heavy‑duty ports commonly found in commercial pools or high‑flow residential setups. Made for repeated seasonal use, it provides a durable and dependable solution for protecting plumbing during winter shutdowns. Based on similar large‑format winterizing plugs with integrated valves, the estimated weight typically falls in the 0.6–1.0 lb range.
