Description and experienceShow

Accurate compression readings help narrow down petrol engine faults without replacing parts on guesswork. This kit is supplied with a pressure gauge rated to 300 psi or 20 bar, five thread adaptors, flexible hose sections, straight and angled pressure tubes, and an extension bar for access around awkward engine layouts. It is listed for petrol engines in cars, motorcycles, trucks, lawn mowers and ATVs, making it a useful diagnostic set for home garages and small workshops. The operating process involves warming the engine, removing spark plugs, opening the throttle and cranking briefly while watching the gauge. Repeat tests can then be compared across cylinders for a clearer picture.

The image shows a blue plastic case opened to reveal a pressure gauge, hoses, metal tubes and several threaded adaptors. A Union Jack badge and large 11PCS text are printed on the product artwork.

Guarantees, usage and supportShow

Technical review and performance

The set combines metal fittings with rubber hose sections for flexible access to spark plug ports. The 75 mm gauge face and dual bar/PSI mode support quick reading during repeated cylinder checks.

Expert take

The strongest point is the range of fittings in a compact case. Five listed thread sizes cover common petrol engine applications, while the straight tube, angled tube and hose give useful flexibility around tight engine bays. It is a practical choice for DIY diagnosis and small workshop checks, especially when you need repeatable cylinder-to-cylinder comparisons. The set is for petrol engines, so diesel compression testing should be treated as a separate requirement.
