  • 🔧【COMPLETE 13-PIECE COMPRESSION TESTER KIT】This professional compression tester kit includes: 1 pressure gauge, 2 spark plug testers, 1 straight rod, 1 bent rod, 5 metal adapters (M10x1, M12x1.25, M14x1.25, M16x1.5, M18x1.5), 1 extension hose, and 4 rubber O-rings. Designed for gasoline engines only—NOT for diesel.
  • 🔬【HIGH-VISIBILITY FLUORESCENT GAUGE – DAY & NIGHT READABLE】Features a large 2.5" Ø63mm dial with triple-scale readings: 0-300 PSI, 0-20 Bar, and 0-21 kg/cm². The fluorescent dial finish ensures clear visibility in both bright workshop lighting and low-light conditions. With a built-in Schrader valve inside the gauge for stable, reliable peak pressure readings—no extra adapter needed.
  • ⚙️【QUICK & EASY TEST PROCEDURE – 5 COMPRESSION STROKES】Save time and money on mechanic visits. Simply: (1) Run engine to normal operating temperature, then remove all spark plugs and disable the ignition system; (2) Open the throttle to wide open position; (3) Select correct adapter and hand-tighten into spark plug hole; (4) Crank the engine for at least 5 compression strokes until the gauge needle stops rising; (5) Press the quick-release safety valve to reset before testing the next cylinder. Use the 10% deviation rule to identify engine issues. Complete diagnosis in minutes.
  • 🔍【DIAGNOSTIC ACCURACY – 10% DEVIATION RULE】Use the 10% deviation rule for accurate engine health assessment: compare readings across all cylinders—a deviation of more than 10% between the highest and lowest readings indicates potential engine problems. The built-in Schrader valve ensures stable, reliable peak pressure readings every time. Includes 2 spark plug testers for quick ignition system troubleshooting—simply connect between spark plug and plug wire, start engine, and observe the spark to detect defective cables or connections.
  • 📦【DURABLE METAL ADAPTERS & STORAGE CASE】Built with high-quality metal adapters and durable hose for workshop-grade reliability. Quick-release safety valve allows safe one-handed pressure release after each test. Includes 4 rubber O-rings for secure sealing. All components neatly organized in a protective carrying case for easy storage and portability. Ideal for professional mechanics and DIY enthusiasts.
