Looking for advice?
The Pentair Triton NEO Large O-Ring (R152501W) is the original replacement closure O-ring for the Triton NEO sand filter lid. This large EPDM O-ring provides the primary watertight seal between the filter lid and the tank body. A worn or damaged O-ring is the most common cause of lid leaks — replacing it immediately solves the problem.
Pentair Triton NEO O-Ring (Large) – Reference R152501W
The Pentair R152501W Large O-Ring is the genuine replacement closure O-ring for Triton NEO sand filter lids. This single O-ring forms the primary pressure seal between the filter lid and the tank body. Under normal operating pressure, a healthy O-ring keeps the filter completely watertight. Over time, however, exposure to UV, heat, and pool chemicals causes the rubber to harden, crack, or deform — resulting in leaks around the lid.
Most Common Cause of Lid Leaks — Solved in Minutes
Replacing this O-ring is the first step in any Triton NEO lid leak diagnosis. Remove the lid, clean the O-ring groove, apply a thin coat of silicone grease, and seat the new O-ring. Refit the lid, prime the system, and the leak is resolved — the entire procedure takes under ten minutes and requires no tools.
EPDM Rubber for Long Service Life
The R152501W is made from EPDM rubber, chosen for its outstanding resistance to chlorinated water, UV radiation, ozone, and temperature extremes. EPDM maintains its flexibility and seal integrity far longer than standard NBR rubber in pool water environments.
