The pressure tester blends a traditional European tester with a machined end designed for "Stant" type radiator adapters. This unit features a very accurate rubber protected gauge that measures in bar as well as psi. It comes in a rugged fitted case. This unit costs more than the Stant and or other similar units that are made overseas or in Mexico(Stant),it represents a greatly improved design. The protected gauge and the hard impact restant body are matched by the precision internal components. It has a presure release valve located on the back side of the pump opposite the gauge. It is very easy to pressure up the cooling system. Since the unit has a quick coupler that connects to the "Stant" style adapters, it can also be easily converted to other uses i.e. a hand pressure pump etc. Note: We have specifically ordered this pump set up so that our customers do not have to reorder new radiator adapters. It will work with any adapter that fits a "Stant" style cap.During our introduction of this item, we will offer a $10.00 discount on any radiator adapter ordered at the same time. <BR<BR<BR<BRAlso check out the new KOOL TEC Cooling System Test Kit.
