PTR 1300


The PTR hydraulic pressure tester or test bench allows for the quick and easy detection of fissures and cracks and the water tightness control in the cooling circuits of cylinder heads and engine blocks. The pressure tester works following a basic principle that consists of plugging all the outlets of the cooling circuit of the cylinder head using rubber stoppers and then injecting pressurized air into the circuit. The cylinder head is then immersed in a hot-water bath and if it contains any cracks or fissures, a stream of air bubbles will be observed rising to the surface of the bath.
