Accu-Glass metal-gasket tube fitting feedthroughs are terminated with VCR® metal gasket face seal fittings. 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. Please consult Swagelok's VCR specifications and installation guidelines for best results.
These are general purpose, non-cryogenic, tube feedthroughs used for gas and/or fluid coolant delivery into high and ultrahigh vacuum systems.
Accu-Glass Products fluid feedthroughs are available in single or dual tube configurations, with 1/8 or 1/4 inch tube diameters. Standard feedthroughs are offered with fittings TIG welded on both tube ends. Bare-tube terminations are often required when there is no space for a fitting joint — or a demountable joint is just not allowed, and where direct welding to stainless steel supply-lines is the preferred solution.
