Carpet Cleaner, Pressure Washer & Car Wash Qc: The brass ISO-B quick connect used on truckmount extractors, carpet cleaning wands, pressure washer hoses and car wash equipment. Dixon H3F3-B is the 3/8" plug half of an ISO 7241-1 Series B quick connect. Mates with any ISO-B coupler, including Foster FHK, Breco DS, hpcouplers ISO-B and Aeroquip FD56 style.
Rated To 2,200 Psi: Brass body with two-way poppet valve. Shuts off flow in both directions on disconnect, so lines stay full and spill is minimal.
3/8" Female Npt Thread: Threads straight onto 3/8" pipe or hose fittings. No adapter needed on most water, coolant and hydraulic lines.
Brass For Water And Coolant Service: Working temperature -40°F to +225°F with Buna-N seals. Brass resists corrosion in water and coolant lines where steel would rust.

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
