Genesis offers hoses and hose sets for a variety of lengths and configurations. All hoses are pre-charged with high purity helium and utilize refrigeration fittings for easy leak-tight connection to the cryopump and compressor. Hoses can be purchased in sets of two (supply and return) or as singles. Hoses are available in ½" or ¾" diameters (I.D.) and in lengths ranging from 3 to 60 feet. Genesis can provide any combination of elbows or straight connections.
