Pentair 273513 O-Ring - #2-109, PTFE Coated, Air Bleeder Screw, TR100C, TR140C

What This Part Is Used For
The Pentair 273513 O-Ring is used on the air bleeder screw in TR100C and TR140C filter systems. It creates a seal that allows trapped air to be released without water leaking out.

Why This Part Matters
A worn bleeder O-ring can cause small but persistent drips from the top of the filter. That can introduce air into the system or create corrosion over time. Replacing the seal keeps the air relief functioning properly and leak-free.
