COMPATIBILITY & APPLICATIONS
Fits Standard 2.5 Inch Housing Systems
These O-rings are engineered for IPW Industries and AO Smith whole house filter housings that accommodate standard 2.5 inch diameter filter cartridges. The 3.44 inch actual diameter ensures proper fit in housings like the AO-WH-PRE and AO-WH-PREV models. Replace the O-ring each time you change your sediment filter cartridge to prevent leaks and maintain system integrity. Compatible with most major brands using the standard 2.5 inch housing specification.
💧 Replace your O-ring every time you change the filter cartridge. A worn or compressed O-ring is the most common cause of housing leaks, and a fresh seal costs far less than water damage.
