The R&D Cylinder Leakdown Test Kit for four stroke engines is the fastest and most accurate method to test and verify the condition and performance values of a four stroke engines cylinder, pistons, intake, and exhaust valves. Simply find top dead center on the compression stroke of the cylinder and insert the cylinder test kit and inject air into the cylinder. The percentage of leakdown will instantly be displayed on the gauges. Accurately test for cracked or detonated pistons, leaking ring sets, and leaking intake or exhaust valves. The R&D Leakdown Kit is more accurate than Snap-On, Matco, or Mac Test Kits as the R&D second gauge reads in P.S.I. and not a large window range displaying only good, fair, or poor rating. The R&D Kit comes with comprehensive directions that has a calibration chart enclosed that will display leakdown percentage at 100, 90, and 75 P.S.I. ratings. The R&D Leakdown Test Kit is accurate, fast, and efficient. Kits are available in 10 mm and 14 mm threads, and optional adaptors are available.
