About these items Designed for precise engine diagnostics this compression tester kit features a large 80 mm dial gauge with clear dual-scale readings for quick interpretation. Model YS-045 measures from 0–1000 psi and 0–70 bar making it ideal for high-compression diesel engines while Model YS-103 offers a 0–300 psi and 0–2000 kPa range suited for gasoline engines. The shock-absorbing rubber cover enhances gauge protection during daily workshop use and transport. This engine compression tester set includes either 18 specialized adapters in Model YS-045 or 9 adapters in Model YS-103 providing flexible compatibility across a wide range of vehicles. The diesel-focused YS-045 includes injector adapters glow plug adapters and screw adapters suitable for trucks tractors motorcycles and other diesel-powered equipment. The YS-103 gasoline version supports 10 mm 12 mm 14 mm 16 mm and 18 mm thread sizes including long reach and deep well connectors for enhanced accessibility. Equipped with a 19.6' hose on Model YS-045 and a 25' hose on Model YS-103 this compression test kit allows flexible positioning during engine inspection. The extended hose length makes it easier to access deep or confined engine compartments while maintaining a clear view of the pressure gauge. Quick-connect components support smooth attachment helping technicians operate the tool at different angles without compromising accuracy. The flexible rubber hose is designed to withstand high pressure and temperature variations ensuring stable airflow transmission during testing. Built with sturdy brass connectors and reinforced rubber hoses this cylinder pressure tester is engineered for long-lasting durability. The corrosion-resistant metal components help maintain structural integrity even in demanding workshop environments. Model YS-103 also includes a replaceable sealing accessory kit with seal rings and internal valves minimizing concerns about wear leaks or aging parts over time. The secure adapter fit combined with reliable sealing performance ensures accurate compression readings without pressure loss. Each compression tester kit is supplied with a dedicated plastic storage case that keeps all gauges hoses and adapters neatly organized. The compact case dimensions allow convenient storage in tool cabinets vehicle trunks or workshop shelves while protecting components from dust and impact. Clearly arranged compartments help users quickly identify and select the correct adapter reducing setup time during diagnostics. The lightweight yet robust design makes transportation between job sites easy while maintaining component protection. Whether used in professional automotive service centers home garages or field repairs this organized kit structure enhances efficiency convenience and tool longevity.
