Sight Gauge Tank Extension

Atkinson Sight Gauge Tank Extension


If you are fitting this to a plastic tank the the outlet will be recessed and you will require an extension fitting to ensure the Atkinson Tankmaster Valve does not foul the end of the tank and prevent installation.

These are 1″ male BSP with a back nut one end and 1/2″ BSP female the other end for connecting either a Tankmaster Valve or a Push button Sight Gauge.

Extension pieces are available in:

  • 1 1/4″
  • 3 1/2″
  • 6 1/4″
  • 7 1/4″
