## Summary description

Compression pressure gauge with adapter set from NEO Tools (model TOP-11-261). Mechanical gauge designed to measure cylinder compression pressure in engines, supplied with a set of adapters for different spark plug and injector thread sizes. Suitable for diagnostic testing of petrol and diesel engines, workshop inspections, maintenance checks and troubleshooting compression-related faults.

## Long description

The NEO Tools compression pressure gauge with adapter set is a mechanical diagnostic instrument designed to measure cylinder compression pressure in petrol and diesel engines. The kit includes a hand-operated gauge and a selection of threaded adapters to fit common spark plug and injector ports, enabling direct readings from individual cylinders. This tool provides a straightforward method for assessing engine health, identifying worn rings, leaking valves, head gasket faults or other compression-related problems without requiring electronic equipment.
Advantages
The gauge delivers clear analog readings on a circular dial, allowing rapid interpretation of peak compression pressure and relative cylinder-to-cylinder variation. Included adapters expand compatibility across a range of engines, reducing the need for additional fittings. Its mechanical construction requires no batteries or external power, and the durable housing is suitable for workshop conditions. The kit is compact for easy storage and transport.
Suitable for
Routine engine maintenance and inspection
Diagnosing low compression causes such as worn piston rings or damaged valves
Comparative cylinder testing after repair or rebuild
Pre-purchase vehicle checks and workshop diagnostics
Key specifications
Measurement type: mechanical compression pressure gauge
Display: analog dial with pressure scale suitable for automotive cylinders
Adapter set: multiple threaded adapters for common spark plug and injector ports
Power: manual operation, no batteries required
Construction: metal and reinforced plastics for workshop durability
How to use
Warm the engine to normal operating temperature, then disable ignition and remove the spark plug or injector to access the cylinder. Select the correct adapter and thread it securely into the spark plug or injector hole. Connect the gauge hose and ensure a tight seal before cranking the engine several times with the starter to obtain peak pressure readings. Record the peak value for each cylinder and compare results to manufacturer specifications or between cylinders to identify discrepancies. After testing, carefully depressurize the gauge, remove the adapter and reinstall spark plugs or injectors following correct torque procedures.
Usage recommendations
Perform tests with the engine at normal operating temperature, disable ignition to prevent the engine from starting, and follow vehicle manufacturer safety procedures. Use the appropriate adapter for a secure seal and avoid cross-threading. Compare readings across all cylinders and consult engine service limits when interpreting results.
