Universal Compression Tester Kit

Brief Overview

This universal compression tester kit delivers quick, reliable cylinder pressure readings on engines where spark plug access is challenging or deeply recessed. The kit includes everything needed for compression diagnostics across a wide range of engine configurations. For shops that diagnose multiple engine types, consider pairing this with a diesel-specific compression testing set to cover alternative fuel engines, or an oil pressure diagnostic kit to provide comprehensive engine health assessment services.

Key Features

• 0–300 psi (0–21 bar) analog gauge with pressure-relief valve for safe operation
• Air-hold valve for easy gauge reset between test cycles
• Four brass threaded adapters in assorted sizes to fit different spark plug holes
• Two aluminum extension tubes with black rubber protective tips for accessing recessed spark plugs
• Flexible rubber hose with quick-connect metal fittings for secure coupling
• Durable carrying case with molded compartments for tool organization and job-site portability
