Description

Car Exhaust Back Pressure Tester Gauge Meter DiagnosticTool Catalytic Converter
Car Exhaust System Back Pressure TesMain Usage:Test the pressure in the front of catalytic converter to determine whether the exhaust is blocked;
Adaptor fits into oxygen sensor hole enabling back pressure of mufflers and catalytic converters
Pressor Gauge adapter threads into oxygen sensor ports (both M12 12mm and M18 18mm). Test at idle and at2500 rpm's. Pressure should be below 1.25psi at idle and below 3psi at 2500rpms.It can also be used for additional purposes, such as intake manifold vacuum test, cylinder and fuel pump pressure test.It must match the right joint(package not include);
Higher readings indicate a restriction which should be corrected.
Specification:Pressure gauge readings in psi and bar. Positive pressure range 0-14psi. Negative pressure range 0-25inHg. It can also be used for additional purposes, such as intake manifold vacuum test, cylinder and fuel pump pressure test.It must match the right joint(package not include); Quantity:1 x pressure gauge, 1 x high-pressure hose, 2 x connection joint, 2 x clamps, 1 x users manual
