DHA Engine Cylinder Leak Down Tester Kit is an automotive diagnostic tool for checking cylinder leakage and pinpointing common faults. Peace of mind for home mechanics and professional workshops who need a quick, reliable way to confirm worn rings, valves or head gasket issues. Will the kit cover the engines in your garage?
⚡ At a Glance
- • Leak Detection: Dual-scale gauges display 0-7bar and 0-100psi with percent leakage readout for clear diagnosis
- • Best for: DIY enthusiasts and professional mechanics diagnosing petrol engines with 12mm or 14mm spark plug threads
- • Not ideal for: Engines that do not have 12mm or 14mm spark plug thread sizes
Dual-pressure gauges read 0-7bar and 0-100psi with an accuracy of ±2.5%. Flexible hose, quick connector and multiple adapters fit common spark plug threads for straightforward testing.
Pinpoint cylinder leakage - with dual-scale gauges and percent readout
Dual gauges display pressure in bar and psi while the percent leakage scale reflects loss relative to sealed pressure, measured via the spark plug thread. Accuracy is specified at ±2.5%, allowing repeatable readings for comparative diagnostics.
Identify worn piston rings, leaking valves or head gasket faults without dismantling the engine, so time-consuming strip-downs are avoided unless necessary.
Wide fitment for petrol engines - with multiple adapters for common spark plug threads
Adapters include sizes to suit popular plug threads, and the quick-connect fitting joins the flexible hose to the gauge assembly for a secure seal. The gauge set is aimed at petrol engines using 12mm and 14mm spark plug threads.
Work across a range of cars, motorcycles and light-duty trucks without hunting for specialist fittings, speeding up diagnostics in mixed fleets.
Built for workshop use - with rubber-protected gauges and hard carry case
Gauges include rubber covers that resist knocks and scratches, while a rigid case stores gauges, hose and adapters neatly. The flexible hose is designed for repeated connection and disconnection via a quick connector.
Rugged protection keeps instruments accurate and portable, making the kit easy to store and resilient enough for everyday garage handling.
