ORDER: Isolation Valve Key


Vaillant & Glowworm isolation valve key




This key fits the isolation valves on both Vaillant and Glowworm boilers in the centre hole as pictured. We recommend you use this key if your boiler is a few years old as the valves can become very stiff and difficult to fully close since the screwdriver slot provided is too shallow.

Purchase price includes 1st class post.
