Description Cylinder leak down tester,compression test kit -Engine Cylinder Dual Gauge Leakdown Tester kit Diagnostics Tool Designed to detect a variety of common engine faults such as worn piston rings, cylinder head cracks, worn valves and blown head gaskets. It checks the amount of leakage in an engine cylinder and helps determine the source. Gauge scale displays percentage of cylinder leakage and cylinder pressure. Pressurized air is supplied to each cylinder and in moments displays a rate of leakage measure from 0 to 100% Suits all local and imported cars and trucks, designed to check the amount of leakage in 4-stroke engines. Ideal for testing trucks and car models where clearance is minimal. This is a high quality TU-21 cylinder leak detector, including double gauge system, 2-1/2" input pressure gauge, snap-on quick connect male connector, gauge scale 0-100PSI, 10mm,12mm, 14mm spark plug adapters, air regulator and carry case.
