Upgraded with six premium adapter components, this comprehensive 3-in-1 Cylinder Compression Tester and leak-down kit delivers maximum configuration flexibility for complex shop environments. By expanding on the standard setup with heavy-duty push-on connectors, threaded adapters, and long-reach extension rods, it stands as an essential, high-ROI investment for any professional mechanic or commercial workshop.
Product Features
High-Precision Dual Diagnostics:
This TU-21 Cylinder Compression Tester delivers simultaneous, real-time readouts of cylinder pressure (0–100 PSI/0–7 BAR) and leakage percentages (0–100%) to drastically reduce diagnostic diagnostics time. When paired with a workshop air compressor, this commercial-grade tool allows technicians to instantly identify critical internal engine faults, including worn piston rings, cracked cylinder walls, and blown head gaskets.

Industrial-Grade Threadless Connection:
Built with premium aluminum and rugged rubber, the universal straight and angled push-on connectors bypass spark plug threading to maximize shop efficiency across virtually all gasoline engines. Combined with an M14 extension rod, dual-length hoses, and heavy-duty, deep-threaded adapters (M10–M18), this setup ensures secure, slip-free operations even in deep-set cylinder configurations.

Streamlined Pneumatic Control:
This TU-21 Cylinder Compression Tester assembly features an integrated industrial air regulator valve and a 1/4" standard air quick-connect plug for rapid, seamless shop compressor integration. The secure "pull-to-adjust, push-to-lock" pressure knob provides technicians with precise, reliable airflow control, preventing accidental configuration shifts during heavy-duty fleet diagnostics.
