With a 0 to 400 psi range and a 3-1/2" (88.9 mm) dual-scale gauge, this pressure tester measures oil pressure in automatic transmissions and gasoline engines for most domestic and imported vehicles. It utilizes six feet of oil-proof nitrile hose and includes standard and metric fittings to reach various test ports on cars and light trucks. The gauge dial includes an expanded lower scale to provide precise readings at low pressures where dashboard indicator lights lack detail.
