‘O’ Ring Needle Valves





Constant request from users for a needle type stopcock have led to the development of this valve, which incorporates a P.T.F.E. piston sealed as the ‘O’ Ring Tap with a P.T.F.E. needle shut off point. Calibrations on barrel give indication of flow to enable you to repeat.
