General service fluid feedthroughs are used to deliver gases and/or cooling liquids into high and ultrahigh vacuum systems. Our feedthroughs are available in single or dual tube configurations, with 1/8 or 1/4 inch tube diameters. Feedthrough tubes are terminated with Swagelok standard compression (swaging) fittings, or metal-gasket-fitted, ultrahigh-vacuum-rated VCR® fittings.
Swagelok® fittings are demountable, gas-tight cold-formed (swaged) mechanical joint between a tube's OD and the ferrules housed inside each fitting. Tube finish, temper and wall thickness are all critical parameters for making reliable, gas and vacuum-tight seals.
VCR® fittings are zero-clearance, demountable UHV compatible mechanical joints produced by crushing a deformable metal gasket between two mating and polished fitting gland faces. Fitting gland finish, and metal gasket temper are critical parameters for making reliable, gas and ultrahigh vacuum seals.
These are general purpose, non-cryogenic, tube feedthroughs used for gas and/or fluid coolant delivery into high and ultrahigh vacuum systems.
