About This Item
OEM Quad Seal for Pentair Triton II and Tagelus Sand Filters
The Pentair 152516Z is the OEM replacement quad seal for the valve adapter on Pentair Triton II and Tagelus fiberglass sand filters. If your filter's multiport or valve adapter connection is weeping water or losing pressure at the valve interface, this is the seal that restores a leak-free fit.
A quad seal uses a four-lobed cross-section profile — rather than the round profile of a standard O-ring — to provide a more stable, higher-contact seal under dynamic valve movement. In sand filter applications, it seats between the valve adapter and the filter tank port, maintaining a positive seal through repeated backwash cycles and pressure fluctuations. Replacing a degraded quad seal eliminates bypass leakage at the valve connection point and restores full system pressure integrity.

Pro Tip
Before ordering, locate the part number stamped or molded on your existing seal and confirm it reads 152516Z. If your valve adapter connection shows weeping at the filter tank port rather than at the valve handle or rotor, this quad seal is the correct service point to inspect first.
