CTI 8043074 Cryopump Helium Compressor Lines Aeroquip 5400-S5-8 10 ft Pair

CTI 8043074 Cryopump Helium Compressor Lines Aeroquip 5400-S5-8 10 ft Pair

This is a pair of CTI-Cryogenics 8043074 helium compressor flex lines, each approximately 10 feet long, fitted with Aeroquip 5400-S5-8 refrigerant quick-disconnect couplings. The hoses are color-coded red and green to identify supply and return lines, a standard convention on CTI cryopump systems. Construction is stainless steel braided flexible hose, designed to carry high-pressure helium between a cryogenic compressor and a cryopump cold head.

Applications

CTI-Cryogenics helium compressor flex lines connect the helium compressor unit to the cold head of a cryopump, carrying high-pressure and low-pressure helium gas through the refrigeration cycle that cools the pump to cryogenic temperatures. These lines are standard consumable service parts on CTI cryopump systems widely used in semiconductor fab equipment — including ion implanters, physical vapor deposition (PVD) chambers, CVD systems, and other high-vacuum process tools — as well as in research accelerators and scientific vacuum systems. The Aeroquip 5400-S5-8 quick-disconnect couplings allow the lines to be connected and disconnected without losing helium charge, simplifying maintenance and cold-head swaps. Ten-foot lines are a common length used where the compressor sits adjacent to or beneath the process chamber. Compatible CTI compressors include models such as the 8500, 8200, 9600, and similar units that use the standard Aeroquip refrigerant coupling interface.
