Captain O-Ring Rebuild Kit for Pentair Air Relief Valve 98209800/98209803/98209804 (5 Sets, 15 O-Rings)

Extend the life of your Pentair air-relief valve

The Captain O-Ring rebuild kit is a purpose-built solution for Pentair air-relief valves 98209800, 98209803, and 98209804. This kit bundles five complete sets and a total of 15 o-rings, giving you a ready-to-use rebuild option that travels neatly in a service cart or toolbox. Each component is packaged to stay organized during maintenance, so you can find the right piece quickly when you need it.

Designed for real-world use, the kit uses OEM-spec synthetic rubber that resists deformation and maintains a tight seal under typical filtration loads. The large o-ring is intended for the bottom valve threads where the valve attaches to the filter tank, while the small and medium o-rings fit onto the valve stem. Each piece is sized to match Pentair's original geometry, helping you restore compatibility without guesswork. The material feels firm yet flexible, with a clean, consistent snap when seated correctly.

Why this matters in practice

• Five sets ensure you can service multiple intervals without reordering mid-cycle
• Fifteen o-rings cover all required seals for standard rebuilds, reducing downtime
• OEM-spec material supports consistent compression and durable performance across seasons
• Assembled in the USA with a warranty from Captain O-Ring, signaling accountability and support

Real world use cases

• Prevent leaks during peak filtration demand by refreshing seals before wear accelerates
• Restore smooth, predictable valve operation after long storage or seasonal inactivity
• Equip a maintenance team with a single, reliable rebuild solution that fits multiple Pentair models
