Leak testing for components and assemblies is a requirement in both the automotive and the refrigeration industries, but the leak specifications, methodologies, and associated costs are substantially different.
Advanced technology for leak testing now provides opportunities to improve quality and save money even in applications where expensive helium systems are customary.
Rings that do not seal, porous metals that leak fluid and tubes with holes can result in parts malfunctioning causing millions of dollars in damage, and even loss of life.
