SW-4 Big Blue Water Filter Housing Wrench

Sale price$7.00


The SW-4 Big Blue Reverse Osmosis Housing Wrench is designed to work with most Big Blue filter housings. It works best for filter replacements to make them more accessible and help prevent housing breaking. This wrench should be used to unscrew the housings only and not to over-tighten to avoid cracking the O-ring seal.
