## Long description

The Rockforce RF-902G3 Compression and Vacuum Tester — 4-piece set is a handheld diagnostic kit designed to check engine cylinder compression and intake manifold vacuum. The set combines a compression gauge and vacuum gauge with a selection of fittings and hoses to measure pressure differentials and assist in identifying issues such as leaking valves, worn piston rings, or intake leaks. The kit is suitable for use in workshops and field service on petrol and diesel engines where routine or troubleshooting compression and vacuum checks are required.
Advantages
The Rockforce RF-902G3 set offers a compact, portable arrangement of gauges and adapters that allows direct measurement of cylinder compression and intake vacuum without complex setup. The gauges provide clear, analog readings to help pinpoint mechanical problems quickly. Durable materials and a simple connection system reduce the risk of false readings and support repeated professional use in varying conditions.
Suitable for
Routine compression checks on petrol and diesel engines
Diagnosing worn piston rings, leaking valves, or head gasket failures
Checking intake manifold vacuum for vacuum leaks and servo diagnostics
Workshop maintenance and field service inspections
Key specifications
Handheld analog compression gauge with readable pressure scale suitable for engine diagnostics
Handheld vacuum gauge for intake vacuum measurements
Set of hoses and multiple fittings to adapt to common spark plug and injector ports
Durable construction intended for workshop and field use
How to use
Ensure the engine is at operating temperature and the ignition system is disabled to prevent engine start during testing. Connect the appropriate adapter to the spark plug or injector port, attach the compression gauge hose securely, and crank the engine several compression strokes to obtain a stable reading. For vacuum testing, connect the vacuum gauge to a suitable intake manifold or vacuum port and observe steady-state and dynamic vacuum readings while the engine is idling and during throttle changes. Record readings and compare them across cylinders or against manufacturer specifications to identify abnormalities.
Usage recommendations
Use personal protective equipment and follow vehicle manufacturer procedures. Perform multiple compression strokes per cylinder to ensure consistent readings and warm the engine to normal temperature before testing. Avoid using the same adapter on different engines without inspection and cleaning to prevent contamination. If readings indicate significant variance between cylinders or low vacuum, follow up with leak-down testing or valve and ring inspections.
