Description

Aladdin APCO2372 Pump and Valve Adapter O-Ring

OEM-spec replacement for Hayward SPX4000Z1, Pentair 274494, and Sta-Rite U9-374.

The Aladdin APCO2372 is a Buna-N adapter O-ring that seals 2 in bulkhead unions, pump diffusers, and valve adapters across the Hayward, Pentair, Sta-Rite, Jacuzzi, Harmsco, and Advance lineups. It measures 2.35 in ID by 2.77 in OD with a 0.21 in cross section, so it drops straight into any port spec'd for SPX4000Z1, 274494, or U9-374 without trimming. Aladdin manufactures it to OEM tolerances, and PST stocks it as PST-APCO2372 for same-day shipping.
