About This

• ✅ THREE O-RINGS: Three replacement housing O-rings. The seal is the part that fails on a filter housing, so keeping spares on hand means a cartridge change never turns into a leak.
• ✅ WHAT IT SEALS: The O-ring sits in the groove between the filter housing sump and the cap. It is a rubber sealing ring only - it does no filtering and holds nothing back on its own.
• ✅ FITS THESE PART NUMBERS: Shurflo 9417809. GE WS03X10038 and KWGE25RG. GE housings GXWH01C and GXWH04F. Watts OR-4. CFS is an independent brand - a compatible replacement, not an original manufacturer part. Part numbers are used only to identify the housings this O-ring fits.
• ✅ CHANGE IT WITH THE CARTRIDGE: Replace the O-ring every time the cartridge is changed, or any time the housing weeps at the seam. A flattened, cracked or stretched ring will not seal again once it has been compressed.
• ✅ HOW TO FIT IT: Shut off the water and release the pressure before opening the housing. Wipe the groove clean, seat the new ring flat without twisting it, wipe a little silicone grease around it, then hand tighten the sump.
