The Swimables SW-80-513 O-Ring Kit is a complete seal replacement set designed for Pentair FNS Plus push-pull and slide-style backwash valves. Replacing OEM O-513, this kit provides all necessary O-rings to restore leak-free valve function and ensure proper backwash performance. Each ring is made from durable, chemical-resistant elastomers that withstand chlorine, ozone, and UV exposure. Ideal for routine maintenance or when leaks develop, this kit extends the life of the valve assembly while keeping your pool system efficient.

Highlights

• Complete OEM-Style O-Ring Set: Includes all essential O-rings corresponding to Pentair’s O-513 design, ensuring comprehensive coverage of sealing points. A full set guarantees all areas of the valve are serviced in one replacement.

• Leak-Proof Seal Restoration: Replaces worn or brittle O-rings with new elastomers to stop leaks. A restored seal prevents water bypass and keeps backwash cycles operating efficiently.

• Chemical and Wear-Resistant Materials: Manufactured from premium elastomers that resist chlorine, ozone, and common pool chemicals. This resilience allows the O-rings to maintain sealing ability through repeated use.

• Minimizes Maintenance Downtime: Designed for quick installation without tools or special adjustments, the O-rings drop into place easily. Fast service reduces downtime and gets the filtration system running smoothly again.
