About this item
  • 【Transmission Oil Pressure Gauge】The tester is ideal for testing both engine oil and gearbox oil pressures, allowing you to quickly diagnose potential major engine, oil pressure, or transmission fluid pressure issues on most vehicles.
  • 【500 PSI/35 Bar】A large measuring range (500 psi /35 bar) is equipped with the oil pressure gauge, more suitable for testing big engines of trucks, pickups and vans. Besides automotive oil pressure diagnostic, it is also ideal for testing pressures of more equipment such as small boiler pumps.
  • 【Easy To Use】Remove low oil pressure switch, attach the engine oil pressure tester with the right adapater, start the engine and read the pressure on the gauge. Check if the oil pressure is normal or not by comparing with mauafacturer’s recommended readings. Turn off the engine, remove the tester and replace your low oil pressure switch.
  • 【Pressure Gauge】The gearbox oil pressure tester kit features a 3.5 inch large dial with a shock proof rubber cover to ensure longevity and strength. Dual readings in different colors makes the gauge easy reading, scale range 0-500psi (0-35bar). Please note that there’s no pressure holding function, the gauge pointer will automatically return to zero when the measurement is finished.
  • 【Multiple Adapters】The 42" long hose are made of quality rubber and nylon resin. The hose is pressure resistant and not easy to break. 11 pieces brass adapters (size: 1/4" NPT and 3/8" NPT) are compatible with most brands and models of gasoline and small diesel engine vehicles. Each component are well-organized in a heavy-duty plastic carrying case, facilitating easy transportation and safe storage.

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.
