Hayward PLUG WINTER CMPL 6 PCS

The Hayward Winter Plug Complete 6‑Pack is designed to help protect pool plumbing during the off‑season by sealing multiple lines at once, making it useful for pools with several returns, skimmers, or auxiliary ports. Each plug typically uses a durable expansion‑style design that compresses a rubber seal inside the fitting, creating a tight, reliable barrier that prevents water from entering the pipes during winterization. By blocking water intrusion and maintaining an airtight seal, these plugs help reduce the risk of freeze damage and keep the plumbing system secure until the pool is reopened in warmer months.
