Is it the right tool for your garage needs?
⚡ At a Glance
- • Pressure Range: Dual gauges read 0-100 psi (0-7 bar) and 0-100% leakage, accuracy 0.5%
- • Best for: Mechanics, home DIYers and motorcycle owners diagnosing petrol engines with accessible spark plugs
- • Not ideal for: Users without an air compressor or engines lacking spark plug access
Dual-gauge manifold connects to a user-supplied air compressor to measure cylinder pressure and percentage leakage. Manifold assembly includes an 18-inch hose and an AR2000 pressure regulating valve with multiple adapters for petrol engines.
Accurate Leak Diagnosis – Thanks to Dual Gauges and 0.5% Accuracy
Dual gauges display cylinder pressure in psi/bar and percentage leakage simultaneously, with a stated accuracy of 0.5%. The AR2000 regulator on the manifold controls input air pressure for repeatable tests.
Precise readouts help distinguish worn piston rings from valve or head gasket faults, guiding targeted repairs. Clear measurement makes step-by-step diagnostics faster during in-car or bench checks.
Versatile Fitment – With Universal Push-On and Threaded Adapters
Straight and angled push-on connectors eliminate the need to thread into many spark plug wells, while two threaded adapters and an M14 aluminium extension rod provide additional fitment options. Extension hose and rod can be fitted to long or short hose ends (41-3/4"; 11-1/2").
Adapters cover cars, motorcycles and small engines with spark plugs up to 20mm, reducing the need to source extra fittings. Extension parts reach recessed plugs for easier access in tight engine bays.
Controlled Input and Portability – With AR2000 Regulator and Organised Case
Manifold assembly includes the AR2000 pressure regulating valve and an American-style air plug for straightforward compressor connection. Kit components are supplied in an organised carry case for transport and storage.
Regulation prevents over-pressurising cylinders during tests and supports consistent results across multiple checks. Organised storage keeps gauges and adapters secure for mobile diagnostics or workshop use.
