| Hoses to be used with liquid nitrogen need to be of superior quality. They need to be flexible but not rupture at -196˚C and have high quality welded fittings. Linde Gas Cryoservices offers such hoses in various lengths. Actually, all our hoses have an inner and outer flexible stainless steel hose to offer the required rigidity. Further we add a high quality isolation tube to reduce losses in transfer.
Standard cryogenic hoses have a length of 1200, 1500, 2000 or 3000mm. They will have welded CGA295 LN2 fittings –swivel nuts- on both ends. These fittings are also known as ½” SAE Flare or ¾” 16UNF.
To fill open dewars we suggest a 300mm extension tube with safety grip and a shielded phase separator.
