Compact Inline Filter System Housing Spanner.
This listing is for the Spanner to suit the 5" Compact Inline Filter System
The Spanner is an additional aid to un-tighten and tighten the bottom of the housing to the head when changing the filter cartridges.
It is good practice to lightly lubricate the "O" ring that seals the head to the lower container before tightening the two together, we would recommend food industry grade Silicone Grease for this purpose.
It is important NOT to overtighten the housing
