Pentair 355227 Buna N 70 O-Ring Replacement Pool and Spa Inground Pump

The Pentair 355227 is a precision Buna N 70 durometer O-ring engineered to maintain a watertight seal in Pentair IntelliFlo and Sta-Rite IntelliPro variable-speed pool and spa pumps. Manufactured to AS568-238 specifications with dimensions of 3-1/2" ID x 3-3/4" OD x 1/8" cross-section, this replacement O-ring prevents leaks and maintains pump efficiency in high-pressure inground applications.
TECHNICAL DETAILS

Pentair 355227 O-Ring Specifications

Manufacturer Part Number Pentair 355227
Material Composition Buna N (Nitrile) 70 Durometer
AS568 Standard Size AS568-238
Inner Diameter (ID) 3-1/2 inches
Outer Diameter (OD) 3-3/4 inches
Cross Section (CS) 1/8 inch
Application Type Pool and spa inground pump seals
COMPATIBILITY & APPLICATIONS

Compatible Pentair and Sta-Rite Pump Models

This O-ring fits Pentair IntelliFlo VF (variable flow), IntelliFlo VS 3050 (variable speed), IntelliFlo VS-SVRS, and WhisperFlo pool and spa inground pumps. It is also compatible with Pentair Sta-Rite IntelliPro VS-SVRS variable-speed inground pump models. The Buna N 70 material provides excellent resistance to chlorinated water, common pool chemicals, and temperature fluctuations typical in residential and commercial pool circulation systems. Use this replacement O-ring when servicing pump housings, diffusers, or lid assemblies to restore factory seal integrity and prevent air leaks that reduce pump performance.

💧 Replace pump O-rings annually or whenever you notice water seepage around the pump lid or housing — a compromised seal forces your pump to work harder and can lead to motor damage over time.
