What is an air leak tester?

When manufacturing machine parts or industrial products, the leak test is an extremely important especially for controlling the quality. Methods which submerge a work in water and check the bubbles are commonly used. However, these methods are not suitable for metal parts which are susceptible to water, and may cause leaks to be overlooked. The air leak tester is an alternate method which checks for the presence of fine holes using air.


This air leak tester can be used to inspect products such as engine heads, engine blocks, carburetors, master brakes, brake wheels, transmission, headlights, various pumps, waterproofing devices, piping joints, gas components, drinking bottle caps, food packages, and fishing buoys.
