WNZ Boost Leak Tester Turbo Boost Leak Tester Boost Leak Test kit Boost Leak Tester kit Turbo Leak Tester 9PCS Blue

【Wide Application】:Turbo Leak Tester Kit is designed for checking turbocharging system leaks or cooling system pipes. It helps you to check and locate leaks in turbocharging systems of various vehicles by filling the turbocharging system with low pressure air. The boost leak tester can be used on the turbo in addition to the turbo, but can also be used anywhere an adapter can be mounted, such as for exhaust leak testing as well.
【Simple Operation】:Turbo Leak Tester is simple to operate and can be used with an air compressor with an air storage tank. Insert the plug into the turbo output and air inlet, then use the regulator to connect the plug and air compressor to pressurize the turbo system. Once pressurized, check the gauge to see if it holds pressure with the sound of a leak (if you can't find the source of the leak, you can use a leak sprayer).
[With its own safety valve and regulator] :The leak tester is equipped with a 0-6bar (0-87psi) HD pressure gauge with a shockproof protective cover, which allows you to keep an eye on the pressure inside the hose to prevent it from getting too high. The red manual valve is used to open or close the air pressure. If the air pressure is too high, it can be lowered by pulling the valve (automatic pressure relief when the air pressure exceeds 2.5bar).
[WIDE APPLICATIONS]: The turbo system leak tester kit comes with 4 pairs of stepped adapters made of high quality hard nylon plastic for plugging intake and exhaust pipes. Each adapter is designed with 3 steps to fit most common pressurized hose/pipe sizes, can be used for hose diameters up to 35/40/45/50/55/60/65/70/75/80/85/90 mm, and will hold and seal well, helping you to detect and locate leaks of all sizes.
[Lifetime Warranty]: We have strict requirements on the quality of our products. If the products we sell have quality problems, we will provide a lifetime warranty.

【Easy To Use】Plug the proper adapter into the inlet and outlet of the system. Turn the pressure regulator knob to set your desired pressure. Connect the pressure gauge to inlet adapter, and then connect to the shop air to pressurize the system. After pressurization, you can see if the gauge maintains pressure and listening for any leaks. If the pressure drops, the leaks can be easily found by hand or with spray.
【Warm Tips】When installing the adapter, the adapter connector needs to be locked with a hose clamp, otherwise the adapter connector will loosen or pop out under pressure. The maximum pressure of most vehicle turbocharging systems is approximately 15psi (1bar) to 25psi (1.7bar). Vehicle coolant systems are typically rated for 15psi. (Refer to vehicle manufacturer's data.) NOTE: Excessive pressure may damage system components.
