10"/ 20" water filter housing spanner

Used to open standard sized 10"/ 20" filter housings

A filter housing spanner is an essential tool for opening a filter housing after it has been sealed for a period of time.

This filter housing spanner can be used to open most standard 10"/ 20" water filter housings (except Pentek 3G model filter housings) - to double check please see diagram for the internal diameter of the spanner and the diameter of the teeth on the spanner.

If you do have a Pentek 3G model filter housing, or have a Jumbo 10" / 20"? filter housing, then please see the "accessories" tab for the correct housing spanner.
