The Hydrotech 21401003 Filter Wrench is the perfect tool to help loosen a stuck filter housing and makes changing the filter quick and easy. You should only use the filter wrench to loosen the sump; over tightening the housing sump can damage the O-Rings and make opening the housing more difficult to open later.
- Makes filter change outs fast and easy
- Perfect for loosening a stuck filter housing
- Housing wrenches should only be used to loosen the sump, do not tighten the housing sumps using the wrench
