A petrol cylinder compression tester kit for quick, reliable pressure checks across a range of small gasoline engines, helping spot worn rings or valve issues before they cause breakdowns. Mechanics and weekend DIYers gain confidence from clear, repeatable readings. Could the DHA Petrol Cylinder Compression Tester Kit become the go-to tool in your garage?
⚡ At a Glance
- • Pressure Accuracy: 3-inch diameter gauge with a dual colour-coded scale for clear readings within a 0-300 PSI range
- • Best for: DIY mechanics and small-engine owners who need fast, on-vehicle compression checks
- • Not ideal for: Testing most diesel engines, due to the lower 0-300 PSI range
Schrader-valve connection and a 3-inch dual colour-coded gauge enable quick cylinder pressure checks. The kit includes multiple brass adapters, a 16-inch extension hose, straight and curved connectors, plus a plastic case and English manual.
Clear, repeatable readings - with a 3-inch dual colour-coded gauge
A 3-inch diameter gauge uses two colour bands and a marked PSI scale to separate safe and low pressure ranges, connected through a Schrader valve for direct cylinder access. The 0-300 PSI range covers most gasoline engine needs for quick comparative testing.
Fast visual checks make it easy to compare cylinders and spot problems such as worn rings or leaking valves. Repeatable measurements help track engine health over time.
Wide fitment across spark plug threads - thanks to supplied brass adapters
Brass adapters come with metric male fittings and O-rings, listed as M10, M12, M14, M16, M18, allowing connection to many common spark plug hole sizes and depths. Both straight and curved connectors provide access in cramped engine bays.
Adapters reduce the need for additional fittings, so most motorcycles, cars, ATVs, lawn mowers and chainsaws can be tested without improvising connections. Curved and straight leads make awkward spark plug positions manageable.
Portable and workshop-ready - with a long extension hose and storage case
A 16-inch extension hose links the gauge to the adapters, allowing measurements from outside cramped engine compartments, while all components pack into a supplied plastic case with an English manual.
Carry the kit to roadside or field repairs, or keep it organised in a garage drawer for routine checks. The extension hose means safer, easier access without removing large components.
