Pentair OMNIFilter K4 Replacement O-Ring Kit for OT32 and U30 Housings

• STOP A LEAK AFTER A FILTER CHANGE - The cap-to-sump joint is where an under sink housing usually begins to drip, and renewing the seal is a job that takes about a minute once the housing is already open.
• FITS OT32 AND U30 HOUSINGS - K4 is the O-ring specified in the Pentair OMNIFilter OT32 under sink and U30 installation manuals, and it serves OMNIFilter under sink filter housings of the same size.
• SEATS BELOW THE HOUSING THREADS - It drops into the groove located directly beneath the housing threads; wipe the groove clean and set the ring level so the cap draws down evenly all the way around.
• LUBRICATE, THEN REFIT - Pentair OMNIFilter manuals call for cleaning the ring and its groove and lubricating with silicone grease before refitting, which helps the seal seat properly and release cleanly next time.
• RENEW THE SEAL, NOT THE HOUSING - Check for cuts, scratches or stretching every time you change a cartridge; renewing a worn seal costs a fraction of replacing a housing that has started to leak.
