Cylinder Leak-Down Tester Kit, Dual Gauge 0-100 PSI, 4 Adapters

Cylinder leak-down tester kit helps pinpoint engine cylinder faults fast by comparing input pressure vs. leakage rate for clear, real-time diagnosis on cars and motorcycles. Dual gauges read 0–100 psi to evaluate sealing issues from worn rings, valves, or head gasket leaks. Multi-standard fittings support quick, secure connections to common engine ports, while a compact carry case keeps components protected, organized, and ready for garage or mobile use.

• Delivers dual-gauge readings (0–100 psi) to calculate leakage rate and assess cylinder condition.


• Fits multi-standard US/EU/JP/UK connections for quick hook-up to many engine ports.


• Includes 4 adapters and 2 metal tubes for flexible setup across cars and motorcycles.


• Reduces leak risk with heat-resistant silicone hose and tight-sealing, knurled metal fittings.


• Simplifies testing with a 4-step process: connect, regulate, read, evaluate.

Stop guessing why an engine is losing power, misfiring, or running rough—use this leak down tester to verify cylinder sealing before you tear anything apart. The clear gauges make it easy to compare pressure and leakage at a glance, and the secure fittings help you avoid wasted time chasing false readings. Pack it back into the custom case after each job to keep every part protected and easy to find for the next diagnosis. Grab yours today and test with confidence.
