QMP300WR is a standard Water Filter Housing Wrench that is compatible with all of our standard housings.
Only use wrench to loosen filter housings, never to tighten. Over tightening the housing can cause damage to the O-rings and make re-opening extremely difficult so only hand tighten.
For stubborn filter housings use two wrenches together to get maximum power, where one wrench might not work properly.
