The hpcouplers CA3-3 coupler and PA3-3 plug make a complete 3/8" ISO-A hydraulic quick connect set. Both halves follow ISO 7241-1 Series A, so they also mate with other ISO-A couplers and plugs. Steel bodies, two-way poppet valve, 3/8" Female NPT threads on each half. Rated to 4,000 PSI, -40°F to +225°F.

  • Ag Tip For Tractor Remotes & Implements: The ISO 5675 / ISO 7241-1 Series A tip used on tractor remotes, implement hoses, log splitters and farm equipment. One CA3-3 coupler and one PA3-3 plug per set, matched and ready to connect. Buy the pair once instead of hunting for the mating half.
  • Iso 7241-1 Series A Interchange: Mates with any ISO-A coupler or plug, including Parker 60 Series, Pioneer 8000, Faster ANV and Aeroquip FD45 style.
  • Rated To 4,000 Psi: Steel bodies with Two-way poppet valve on both halves. Shuts off flow in both directions on disconnect, so lines stay full and spill is minimal.
  • 3/8" Female Npt On Both Halves: Threads straight onto 3/8" pipe or hose fittings with no adapter. Working temperature -40°F to +225°F with nitrile seals.

OUR VERDICT

ISO-A is the poppet-style hydraulic quick-connect found on tractors, loaders, dump trucks and plant machinery. Buy it to match an existing ISO-A half; it will not mate with ISO-B or flat face.

WHAT WE LIKE
  • ISO 7241-1 Series A interchange, the poppet style used on ag and construction hydraulics
  • Two-way shut-off: both halves seal at disconnect
  • Case-hardened ball-lock sleeve
WORTH NOTING
  • Connect and disconnect at zero pressure only
  • Only couples with same-size ISO-A halves
