Rubber Compression Plug for Winterizing Swimming Pools & Spas
Prevents Freezing, Expanding Water From Leaking and Cracking Plumbing
Features stainless steel bolts and washers and large plastic wing-nuts to prevent rusting
Safely seal off in-ground plumbing lines during freezing conditions. Winter freeze plugs are used to plug your swimming pool pipes after they have been drained to prevent water from entering the pipes and causing freeze damage.
Simply screw plugs into all return and drain inlets after blowing out lines.
