Cryogenic service fluid feedthroughs are used to deliver gas and/or coolants, such as Liquid Nitrogen LN2, into high (HV) and ultrahigh (UHV) vacuum systems. Feedthroughs are available with single or dual 1/4 inch tube supply lines. Supply lines are thermally insulated by a 1/2 inch coaxial support tube, which creates a vacuum gap around each supply line. Feedthroughs are terminated with Swagelok standard compression (swaging) fittings.
As their name implies, Swagelok fittings produce a 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. Please consult Swagelok specifications and installation guidelines for best results.
