Check safely. Save time. Optimize processes.
Pressure and leak tests are a routine part of automotive development and production. Whether it’s hot testing on engines, cooling system checks, or battery testing in electric vehicles – any leak can have serious consequences. Test engineers, maintenance technicians, and developers face the challenge of creating leak-tight connections quickly and reliably – often under significant time pressure and in confined installation spaces.
