These standard winter pool plugs are available from 1/2 inch to 4 inch pipe. They are non-corrosive and constructed of heavy-duty nylon, stainless steel and high quality rubber. The wing nut turns easily and provides 50% greater tightness than conventional plugs. The rubber expansion plug actually expands when you tighten the wing nut.
Rubber winterizing plugs are vital to closing your pool! They are used to plug your swimming pool pipes after they have been drained to prevent water from entering the pipes and causing freeze damage. Safely seal off inground plumbing lines during freezing conditions. Replace your winter pool plugs whenever any signs of wear occur.
