Description

CTI Cryogenics 8143143 He Compressor Supply & Return Line Pair Aeroquip 5400-S5-4

Matched pair of stainless steel rigid tubing lines for helium compressor systems. Supply line 8143143G001 measures 14" (approximately 19" tubing) and return line 8143143G002 measures 14.5" (approximately 19" tubing), connected via Aeroquip couplings rated for 260 PSIG.

Specifications & What's Included

  • Supply line: 8143143G001, 14" length, Aeroquip 5400-S5-4 female coupling
  • Return line: 8143143G002, 14.5" length, Aeroquip 5400-S2-4 male coupling
  • Inlet thread: 1/2"-20; Outlet thread: 5/8"-18 UNF
  • Hex nut size: 0.75" (3/4")
  • Material: Stainless steel rigid tubing
  • Pressure rating: 260 PSIG

Applications

These lines connect to CTI Cryogenics helium compressors and cryopump systems used in laboratory and industrial cryogenic applications. They handle helium gas supply and return circulation in closed-cycle refrigeration systems. The rigid tubing and rated couplings maintain system integrity under operating pressures typical of helium compressor installations.

Condition: Used
This CTI Cryogenics 8143143 helium compressor supply and return line pair has been inspected and is in good used condition. Both lines were pulled from a working cryogenic system where they were in active service. The stainless steel tubing is intact with no visible kinks or damage, and the Aeroquip coupling fittings on both the supply (5400-S5-4 female) and return (5400-S2-4 male) ends show normal service wear consistent with use in a cryogenic environment. The orange identification band is present. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
