About this item
  • 【Universal Fitment】Suitable for any gasoline / petrol 4-stroke engines with 10, 12 or 14mm spark plugs. The engine leakdown tester checks the amount of leakage in an engine cylinder and helps locate the source. Ideal for testing trucks and late model cars where clearance is minimal.
  • 【Easy to Read】The dual gauge leakdown tester is convenient to test the pressure and leak rate of the cylinder at the same time. Ranging from 0-100 psi / 0-7 bar and 0-100%(Accuracy: ±0.5%) Each gauge is 3 inch(7.62cm) in diameter.
  • 【Working Principle】After the cylinder leak tester is connected to one of the cylinders, the compressed air is sent into the particular cylinder through the pressure regulator. You can find the leak source by observing the cylinder leak gauge and listening to the sounds at different parts of the cylinders.
  • 【Quality Material】The leakdown tester kit is of solid construction. The adapters are made of quality alumium and brass coated aluminum. The hoses are made of premium rubber nylon resin, which stands pressure and not easy to break.
  • 【Package Content】1*480mm flexible hose, 1*12mm spark plug adapter, 1* 14mm spark plug adapter, 1*M14 x 26mm fixed short connector, 1*M16 x 26mm fixed long connecto, 1*pressure and cylinder leakage gauge with air regulator, 1*carry case.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
