Big Blue Wrench

Easily remove large water filter housings, like the Big Blue series, with this Pentek SW-3 wrench! It is for use with most standard 10" x 4.5" and 20" x 4.5" filter housings from name brands including Pentair, Pentek, Ametek, US Filter, and Culligan.

To use, slide the wrench over the bottom of the filter housing until it fits snugly against the unit, and rotate the wrench. The tool's small plastic teeth will catch in the housing's edges and loosen the canister.

This wrench is only to be used in casing removal. Reassembly should be done by hand to avoid damaging the seals.

This is a clearance item with limited inventory. All sales final - no returns.
