Swimming Pool Winterizing Plugs

We offer a variety of rubber and threaded plugs for winterizing your pool. Protect pipes from filling with water and freezing with these plugs.

• Winter plug sets usually include plugs for return lines, skimmers and pool cleaner lines, if applicable
• Rubber expansion plugs are for use in the pool, not on the pool's equipment or filtration system
• For tapered rubber plugs, turn the plug around to adapt for use in different-sized pipes

All rubber pool plugs:

• Are made with quality rubber, an oversized nylon wing nut, and 316 marine-grade stainless steel washers and through bolt
• Are used to prevent pipes from filling with water and freezing during winter months
• Can be used to plug pool returns, skimmers and cleaner lines

The threaded skimmer plug:
