The hpcouplers 2H-S coupler and 2K-S plug make a complete 1/4" ISO-B hydraulic quick connect set. Both halves follow ISO 7241-1 Series B, so they also mate with other ISO-B couplers and plugs. Steel bodies, two-way poppet valve, 1/4" Female NPT threads on each half. Rated to 3,700 PSI, -40°F to +225°F.

  • Industrial Hydraulic Quick Connect: Used on hydraulic power units, presses, test stands, machine tools and chemical transfer lines. One 2H-S coupler and one 2K-S plug per set, matched and ready to connect. Buy the pair once instead of hunting for the mating half.
  • Iso 7241-1 Series B Interchange: Mates with any ISO-B coupler or plug, including Foster FHK, Breco DS, Dixon H-Series and Aeroquip FD56 style.
  • Rated To 3,700 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.
  • 1/4" Female Npt On Both Halves: Threads straight onto 1/4" pipe or hose fittings with no adapter. Working temperature -40°F to +225°F with Buna-N seals.

OUR VERDICT

ISO-B is the most common industrial hydraulic quick-connect. Buy it to replace a worn ISO-B half or to build a new line that disconnects clean with no drip and no air in the circuit. Match the body size and thread to the mating half on your equipment.

WHAT WE LIKE
  • ISO 7241-1 Series B interchange, mates with any brand ISO-B half of the same size
  • Two-way shut-off: both halves seal at disconnect
  • Ball-lock sleeve for shock and vibration
WORTH NOTING
  • Connect and disconnect at zero pressure only
  • Only couples with same-size ISO-B halves
