Product Details
✓✅ ABOUT PRODUCT: This water filter wrench has long-lasting polymers for sturdiness and corrosion protection with Heavy strength, and a reusable housing wrench for twisting off water filter housing cylinders.
✓✅ BUILT FOR STUCK SUMPS – A housing that has sat through a season grips hard, and a strap wrench or channel locks will crack the plastic before they break it loose. This wrench cups the base of the sump so the force spreads around the whole rim instead of two points. Wipe a little silicone grease on the O-ring before you reseal and the next cartridge change comes apart by hand.
✓✅CHECK YOUR HOUSING BEFORE YOU ORDER – Housing wrenches are cut to one sump diameter, so match the housing model rather than the cartridge inside it. This one is sized for the 10 inch slim housings that take 9.75 by 2.5 inch cartridges. It will not fit the wide Big Blue housings that take 4.5 inch cartridges, and it will not fit large diameter whole house sumps.
✓✅FITS THESE PART NUMBERS – Direct replacement for the WR100 housing wrench. It fits the FH4200WW12 and FH4200WW12-RV filter housings and the CCI-10-CLW, CCI-10-CLW12 and CCI-5-CLW12 clear housings. These housings are used in RVs, campers and boats and also under counter and at point of entry, so the same wrench covers all of those installations.
✓✅ The standing "match the filter to your water" bullet is about media selection and this product has no media. The slot is better spent on the housing-and-cartridge cross-sell, since a wrench buyer is opening a housing that needs a cartridge.
