10"/ 20" Jumbo Big Blue water filter housing spanner

Used to open Jumbo / Big Blue 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 Jumbo sized 10"/ 20" water filter housings, also known as Big Blue filter housings - to double check if this is suitable for your housing please see diagram for the internal diameter of the spanner and the diameter of the teeth on the spanner.

If you have a slimmer filter housing or standard sized 10" / 20" filter housing, then please see the "accessories" tab for the correct housing spanner.
