CTI Cryogenics 8143073G012 Pressurized Braided Cryogenic Hose 0.75" M-M

CTI Cryogenics 8143073G012 Pressurized Braided Cryogenic Hose 0.75" M-M

The CTI Cryogenics 8143073G012 is a short, pressurized braided cryogenic hose assembly with male-to-male 0.75-inch nut connectors at both ends. It features a stainless steel braided flex body rated for pressurized cryogenic service, with angled end fittings designed for clean, low-loss connections in cryogenic refrigerator plumbing circuits. The Aeroquip hose construction (code 5400-S5-4) is designed for cryogenic fluid transfer at low temperatures under pressure.

Applications

Pressurized braided cryogenic hose assemblies like the CTI Cryogenics 8143073G012 are used in closed-cycle helium refrigerator systems, such as those manufactured by CTI Cryogenics (now part of Brooks Automation / Sumitomo). These hoses connect the compressor unit to the cold head, carrying high-pressure and low-pressure helium gas through the refrigerator circuit that drives cryogenic cooling. They are commonly found in cryopump systems used in semiconductor vacuum processing equipment, including physical vapor deposition (PVD), ion implantation, and other high-vacuum process tools. Short, angled assemblies like this one are typically used in tight compressor or cold head plumbing where a straight connection is not possible. Replacement hoses are a routine maintenance item in facilities operating CTI Cryogenics 8200, 9600, On-Board, and similar cryopump platforms.
