The measure of seal quality is expressed in terms of its leak rate. Leak rates are often stated in units of cubic centimeters per second of helium. Helium is the smallest permanent gas molecule – therefore it’s used to find the slightest of leaks. Insulator Seal’s ceramic-to-metal joining is at the pinnacle of sealing technology so you’ll get the seal you need.
