Swimables Pentair FNS Plus Push & Pull Backwash O-Ring Kit | SW-80-513

The Swimables SW-80-513 O-Ring Kit is an OEM-style replacement set for Pentair FNS Plus push-pull and slide-type backwash valves. Matching O-513, it includes five O-rings designed to renew critical sealing points and prevent leaks. Each O-ring is constructed from chemical- and UV-resistant elastomers, providing reliable sealing under pool operating conditions. Installing this kit restores proper valve function, improves backwash performance, and helps extend the life of the valve assembly.

Highlights

• Direct O-513 Replacement: Packaged to match Pentair’s O-513, the kit includes all O-rings needed for a full reseal. Replacing the entire set ensures complete sealing coverage for push-pull and slide valves.

• Restores Leak-Free Function: Worn seals are a common cause of valve leakage and system inefficiency. Fresh O-rings restore proper sealing, preventing water bypass and ensuring smooth backwash cycles.

• Durable Elastomer Construction: Built from long-lasting, chlorine- and chemical-resistant rubber compounds, the O-rings maintain flexibility. Their toughness ensures consistent sealing even after repeated cycles.

• Quick and Simple Replacement: Designed to fit without machining or modification, the O-rings install quickly. This makes servicing valves straightforward and efficient for both homeowners and professionals.
