With FPM seals are used on the housing and valve seat for the high-vacuum versions. In the UHV versions, the housing is metal-sealed. canning lids stuck on new mason jarsUltra-high vacuum (UHV) is the vacuum regime characterised by pressures lower than about 100 nanopascals (1.0×10 Pa; 1.0×10 mbar; 7.5×10 Torr). UHV conditions are created by pumping the gas out of a UHV chamber. At these low pressures the mean free path of a gas molecule is greater than approximately 40 km, so the gas is in free molecular flow, and gas molecules will collide with the chamber walls many times before colliding with each other.
