HCPS/HIP/DIY Countertop and Under Sink Systems Housing Wrench:
Use for twisting off Doulton countertop and under sink water filter housings.
Do NOT use the Doulton HCPS/HIP/DIY wrench to tighten the housings. Overtightening the housing can cause damage to the o-rings and make re-opening the housing difficult. You should only hand tighten the housing.
