Description:
Designed for testing late model cars and trucks with hard-to-access spark plug ports.
Intended for use on spark-ignited gasoline engines that do not exceed 300 PSI compression. Uses hose-type adaptors that thread into the spark plug hole and
connect at the gauge hose’s quick coupler. Maintains highest compression test reading and
resets to zero with a push-button release valve. Gauge assembly includes 3” diameter gauge, 25” flexible hose with quick coupler. Test range: 0 - 300 psi (0-2000 kPa) in 5 PSI (50 kPa) increments. Gauge displays individual cylinder pressure. Standard Reach Adaptor connects to standard length spark plug threads. Long Reach Adaptor connects to extra long spark plug threads. Adaptors can be used on either flat or tapered spark plug hole seats. Quick coupler connections between hose and gauge for easier use. Includes Compression Gauge and hose assembly, Standard Reach Adaptor (M14 x 1.25), Long Reach Adaptor (M14 x 1.25) and Check Valves (6 each) in Plastic Storage Case.
