• Manufacturer: Waterway 

• Type: Replacement O-ring

The 2-inch Waterway 805-0229 pool o-ring is a Waterway o-ring for the heater tailpiece on heaters and pumps. O-rings work to create water-tight seals and prevent water and air leaks in the filtration system. Over time, o-rings can develop cracks and tears and even lose their shape, which can lead to water and air leaks and damage surrounding equipment. Damaged o-rings should be replaced before damage occurs.
