The Draper 7 Piece Cylinder Leakage Tool Kit is a professional diagnostic tool designed to identify engine faults quickly and accurately in petrol engines. This comprehensive cylinder leakage tester provides mechanics and automotive technicians with the essential equipment needed to diagnose common engine problems without invasive disassembly. The kit features twin 63mm diameter gauges that simultaneously display cylinder pressure (0-100psi/0-7bar) and the percentage of cylinder leakage, allowing for precise fault diagnosis. Both gauges are protected by heavy duty rubber guards to withstand the demands of busy workshop environments. The included adaptors ensure compatibility with direct and indirect petrol engines using 10mm, 12mm, 14mm and 18mm spark plug threads, covering the majority of petrol engine applications. This cylinder leakage tester accurately detects worn piston rings, worn valves, cracked cylinder heads and blown head gaskets, helping to pinpoint the source of compression loss. The 600mm flexible hose provides sufficient reach for comfortable testing across different engine configurations, whilst the 1/4" BSP air coupler ensures straightforward connection to workshop air supplies. The complete kit is supplied in a protective plastic storage case for organised storage and transportation between jobs.
