Description
CTI Cryogenics 8143215 G002 Helium Compressor Supply Line 350 PSIG 20074-002
The CTI Cryogenics 8143215 G002 is a rigid helium compressor supply line used to carry high-pressure helium gas between a CTI cryogenic compressor and a cryopump or cold head. The line is constructed of bent stainless-steel tubing and is rated for 350 PSIG. Each end terminates in an Aeroquip quick-disconnect coupling half — one female, one male — for secure, leak-free connection to the compressor and cryopump circuit.

Applications
CTI Cryogenics (now part of Brooks Automation / Agilent Technologies) helium compressor supply lines like this one are used in closed-cycle cryogenic refrigeration systems. They carry high-pressure helium gas from the compressor to the cold head or cryopump, which is used to achieve the deep vacuum conditions required in semiconductor process chambers, surface analysis instruments, ion implanters, and other high-vacuum systems. The Aeroquip-style quick-disconnect couplings are standard on CTI 8200, 9600, and similar compressor series and allow the helium circuit to be connected and disconnected without venting the entire system. These supply and return lines are precision-bent to route through specific compressor enclosures and are not generally interchangeable across unrelated systems — always verify the part number matches your compressor model before ordering.
This CTI Cryogenics 8143215 G002 helium compressor supply line has been inspected and is in good used condition. It was pulled from a working cryogenic system where it was actively in service. The tube and fittings appear clean with no visible damage; the Aeroquip couplings at both ends are intact. Please note we may have multiple units in stock — the unit you receive may differ slightly from the one photographed but will be functionally equivalent. Please view our photo set and contact us if you have any questions.
