Filter Wrenches, Mounting Brackets & Pressure Gauges
The small hardware that makes a filter system serviceable — the right wrench turns a stuck Big Blue sump off without cracking it, the right bracket holds your housing square to the wall, and a pressure gauge tells you when a cartridge is spent. We stock genuine wrenches, brackets and gauges from Watts, Pentek and PureT, sized to the housings people actually own.
How to choose the right hardware
Match the wrench to the housing. Standard 10"/20" housings, #20 Big Blue and Full-Flow (B-B) series each take a specific wrench — buying by series (WR100, SW-4, WW-FF) guarantees a fit.
Bracket to the housing head. Mounting brackets are keyed to head style and inlet size (like a 3/4" in-head valve) — pick the bracket listed for your housing line.
Gauge before and after. A pressure gauge on the inlet and outlet shows the pressure drop across the cartridge — the clearest signal that it's time to change.
Buy the tool with the housing. New install? Add the correct wrench and bracket now so the first service isn't a scramble.
