AUTOMOTIVE

The world's major automobile manufactures and their suppliers rely on Uson leak detection equipment for fast, accurate and reliable leak testing. With over 40 years in the business, no other company is as well positioned to meet the demanding needs of the worldwide automotive industry.

We provide engineered leak and functional test solutions that achieve maximum flexibility while maintaining the highest quality and production speed for applications that range from complete engines to fuel injectors, bearings, electrical fittings and much more.

Uson leak testers not only perform tests faster than other leak testers, they also ensure the highest accuracy and repeatability. This advantage eliminates false rejects while keeping defective products from the market.

Unrivalled experience with leak testing of engines, cylinder heads, blocks, transmissions, fuel and fuel injection systems, lamps, castings, pumps, motors and more puts us in the right position to satisfy the leak detection needs of OEMs and tier suppliers around the world.
