Engine Compression and Leak-Down Tester Kit, 4 Adapters

Engine cylinder compression tester kit delivers fast, accurate diagnosis so you can pinpoint low compression and air leaks before they become expensive engine repairs. Dual gauges show 0–700 psi compression and 0–100 psi leak rate for a clear picture of cylinder health. Designed for quick-scan readings and secure hookups, this kit helps troubleshoot rough idle, power loss, misfires, and hard starts on cars and motorcycles with confidence.

• Delivers dual-gauge testing to check cylinder compression first, then calculate leakage rate for deeper engine diagnostics


• Includes multiple spark plug adapters plus US/EU/JP/UK fittings to match most gasoline engines and common cylinder layouts


• Seals tightly with heat-resistant silicone hose to reduce leak risk and improve measurement stability during testing


• Locks on securely with knurled metal fittings for tight, corrosion-resistant connections and repeatable readings


• Stores neatly in a custom carry case to keep tools protected, organized, and ready for garage or mobile use

Use this compression and leak-down tester set to confirm valve, ring, and head gasket issues without guesswork. The illustrated workflow makes setup straightforward: run the compression test, then switch to leakage measurement for a more complete assessment. Ideal for DIY maintenance, pre-purchase checks, and routine troubleshooting when symptoms point to cylinder problems. Keep it in your tool kit for quick answers and cleaner repair decisions—grab yours today.
