Key benefits and features Dual pressure units up to 300 PSI or 20 BAR provide versatile measurement for most engines. Large, easytoread dial protected by an acrylic glass cover with scratchresistant coating and rubber shockabsorbing features for durability in busy shops. Quick and accurate compression readings help identify issues such as stuck valves, carbon deposits, worn piston rings, and other engine inefficiencies to maintain performance. Includes multiple rotating and pushin adapters in various sizes, making the kit suitable for most engine cylinders across motorcycles, lawn mowers, cars, and trucks. Professionalgrade and durable construction using ABS, rubber, and brass components designed to withstand daily wear in workshops and garages for longlasting use. What you get and compatibility Engine compression tester kit with a range of adapters (rotating and pushin) to fit a wide variety of cylinder sizes and configurations. Compatible with common engine types found in motorcycles, lawn mowers, cars, and trucks, providing flexibility for home mechanics and professional technicians. Durability and build quality Built for daily use in demanding environments with robust materials: ABS plastic, rubber components, and brass fittings. Specifically designed to endure regular handling, pressurization, and measurement in a workshop setting, ensuring reliable performance over time. Use scenarios Automotive diagnostics: Check a car engine with suspected low compression in one or more cylinders to determine whether worn piston rings or valve sealing issues are present. Motorcycle or multicylinder engines: Compare compression readings across cylinders to pinpoint imbalance, misfiring, or valve seating problems. Lawn mower and small engines: Assess cylinder health on equipment such as lawn mowers or other gaspowered outdoor tools to plan repairs or replacements. Notes The kit emphasizes clear, straightforward readings and broad compatibility without compromising on build quality or measurement accuracy.
