Description

CTI Cryogenics 8143143 5 Pairs Compressor He Supply & Return Lines G001 G002

This listing is for five (5) matched pairs — 10 individual lines total — of CTI Cryogenics helium supply and return lines for cryogenic compressor systems. Each pair consists of one supply line (8143143G001) and one return line (8143143G002), both terminated with Aeroquip low air inclusion refrigerant quick-disconnect couplings. The supply and return lines have different bending profiles to route correctly within the compressor assembly.

    Condition: Used
    This CTI Cryogenics 8143143 5-pair set of helium supply and return lines (G001 and G002) is in good used condition. The stainless tubing is intact with no visible cracks, kinking, or deformation across all 10 lines. The Aeroquip quick-disconnect couplings on both ends appear clean and undamaged — the coupling faces and seals look to be in good shape based on the photos. There is light surface oxidation and handling marks typical of pulled cryogenic hardware, but nothing that would affect service. These are non-powered mechanical lines and have not been pressure-tested at our facility. Please view our photo set and contact us if you have any questions.
