Description

CTI Cryogenics 8143122 He Compressor Supply & Return Lines Aeroquip 5400-S5-4

This is one matched pair of CTI Cryogenics helium compressor supply and return lines, part numbers 8143122 G001 (supply) and 8143122 G002 (return). Each line is a rigid stainless steel tube with distinct S-bend routing profiles and an Aeroquip low air inclusion refrigerant quick-disconnect coupling on each end, rated to 350 PSIG. The two lines are not interchangeable — each has its own unique bend geometry to fit the specific routing within the compressor assembly.

Specifications & What's Included

  • Quantity: 1 matched pair (supply + return)
  • Supply line part number: 8143122 G001 (8143122G001)
  • Supply line length: 14.5 inches
  • Return line part number: 8143122 G002 (8143122G002)
  • Return line length: 16 inches
  • Approximate tubing length per line: ~18 inches
  • Pressure rating: 350 PSIG
  • Supply coupling: Aeroquip 5400-S5-4 Low Air Inclusion Refrigerant Coupling
  • Return coupling: Aeroquip 5400-S2-4 Low Air Inclusion Refrigerant Coupling
  • Coupling hex nut size: 0.75 inch
  • One Aeroquip coupling at each end of each line (two couplings per line)
  • Construction: rigid stainless steel tubing with distinct pre-formed bend profiles

Applications

These helium supply and return lines connect the cold head to the helium compressor in CTI Cryogenics closed-cycle cryogenic refrigeration systems, such as the CTI-Cryogenics 8200 Compressor and compatible cold heads used in cryopump, MRI, and other low-temperature applications. The Aeroquip 5400-series low air inclusion quick-disconnect couplings are a well-established standard on CTI systems, designed to minimize helium contamination and air ingestion during coupling and uncoupling — critical for maintaining the purity and pressure integrity of the closed helium circuit. These lines are commonly needed as replacement parts during compressor service, cold head relocation, or system reconfiguration in semiconductor fab, scientific research, and medical imaging environments where CTI cryogenic equipment is in use.

Condition: Used
This CTI Cryogenics 8143122 helium compressor supply and return line pair is in good used condition. Both lines show normal surface wear consistent with prior service use. The Aeroquip 5400-series quick-disconnect couplings on each end appear intact, with no visible damage to the fittings or tubing. The stainless steel lines retain their original bent profile.
