Waterway Plastics 805-0207 Air Relief Valve O-Ring

What This Part Is Used For
The Waterway Plastics 805-0207 Air Relief Valve O-Ring is a sealing component used within air relief or air release valve assemblies. It creates a watertight seal between mating surfaces to prevent leaks during normal operation. This O-Ring is installed internally and is not visible once the valve is assembled. It is used in pool and spa circulation systems that rely on controlled air evacuation.

Why This Part Matters
A worn or flattened O-Ring can allow air or water to leak past the valve body. This can result in loss of prime, air intrusion, or moisture around equipment. Replacing the O-Ring restores proper sealing without replacing the entire valve. Using the correct OEM size ensures reliable compression and sealing.
