Atkinson Filstop Overfill-Prevention Valve

Designed to fit at the fill point on metal or plastic Diesel tanks, the Filstop physically closes the inlet of the tank should the level in the tank reach the level of its float, this prevents the tank from being overfilled or bursting, and hence reduces the risk of pollution resuting from such an occurrence

Kit comes complete with inner tank sealing Flange, O'Ring, and Locking Nut for use on plastic tanks, the Filstop can also be used on steel tanks with a 2"BSP welded inlet thread, by discarding the flange and screwing directly into the BSP thread, using a thread sealant to lock the valve into position at the required point
