WiMas Leak Down Tester Kit is a workshop tool for identifying cylinder leakage and compression faults, with a dual-scale gauge and three adapters for common spark plug sizes. It helps DIY mechanics and garage technicians gain confidence when pinpointing worn rings, valves or head gasket issues. Is this the practical kit to add to your toolbox?
⚡ At a Glance
- • Measurement Accuracy: Dual-scale dial reads 0–7 bar (0–100 psi) with a colour-coded percentage leakage indicator
- • Best for: DIY mechanics and garage technicians needing quick, repeatable leak-down checks
- • Not ideal for: Shallow-cylinder engines that require depth-specific fittings
Dual-scale pressure measurement and a colour-coded leakage gauge simplify diagnosis. Three adapters and a protective case keep parts organised and portable.
Clear leak readings – With dual-scale dial pressure gauge
Dual graduation measures pressure from 0 to 7 bar (0–100 psi) and includes a percentage leakage scale marked HIGH, MODERATE, LOW and SET for quick visual checks.
Readings identify cylinders losing compression so comparisons can be made cylinder-to-cylinder for straightforward diagnosis.
Fits common spark plug threads – With three brass/aluminium adapters
Three adapters supplied: a 14mm brass-coated aluminium adapter fixed on a long hose, plus 12mm and 10mm aluminium adapters that connect to the 14mm fitting.
Adapters allow testing of gasoline engines with 10, 12 and 14mm spark plugs without extra fittings.
Controlled and safe testing – With built-in regulator and safety valve
Built-in pressure regulator accepts compressed air at 45–100 psi while a safety valve is designed to withstand pressure and exposure to fuel.
Pressure control makes tests repeatable and reduces risk during diagnosis, helping preserve engine components.
✨ The 4 Key Reasons for WiMas Leak Down Tester Kit
- Built-in pressure regulator – Controls input to 45–100 psi for repeatable tests
- Safety valve construction – Withstands pressurised work and exposure to fuel safely
- Rubber gauge protector – Prevents scratches and maintains legibility over long-term use
- Compact storage case – Keeps adapters organised, easy to transport between jobs
