Description: Functional: The Turbo System Leak Tester Kit is designed to accurately detect and locate leaks in most automotive and light truck turbochargers, cooling, and emission systems Application: This Turbo Boost Leak Tester Kit comes with 4 pairs of step up adapters ranging from 1-3/8" (35mm) - 3-1/2" (90mm), suitable for most automotive and light truck turbocharging systems as well as various sizes of cooling system hoses to meet your different needsEasy to use: Insert the appropriate adapter into the system's inlet and outlet. Turn the pressure regulator knob to set the desired pressure. Connect the pressure gauge to the inlet adapter, then connect it to workshop air to pressurize the system. After pressurizing, you can check if the pressure gauge maintains pressure and listen for leaks. If there's a drop in pressure, you can easily find leaks by hand or spray.Material: The Turbo System Leak Tester is made of metal materials ensuring long term wear resistance.Pressure Gauge: Comes with a 0-6bar (0-86psi) pressure gauge that allows you to observe system pressures at a glance. The pressure gauge has a built in regulator; pull it up and turn it to adjust your required pressure then push down to lock it in place. It also features a release valve that prevents overpressure; if pressures get too high they can be reduced by pulling on this valve (automatically releases when pressures exceed 36Psi/2.5Bar) Specification: Material:Metal Color: Black Size Chart: Package Box38cmx28cmx12cm/14.96inchx11.02inchx4.72inch Package Includes: 1 Turbo System Leakage Tester Kit Note: Please allow slightly errors 1-2cm differences due to manual measurement.
