Quick couplings

All quick couplings from REHOBOT have a check valve and are all supplied with seals and protection caps made of metal or plastic.

Screw type couplings (35 l/min) permit a higher flow rate than insert type couplings (6 l/min).

  • “L” in the designation indicate that the coupling is equipped with a locking ring.
  • “D” in the designation indicate that the coupling is equipped with a dust protection made of metal.

1) Addition of nipple AAU436 gives G1/4″ external thread.
2) Removal of nipple AAU436 gives G1/4″ internal thread.
3) Addition of nipple AAI456 gives G1/4″ internal thread.

Coupling AQU10-S has a built-in hose rupture valve.
Coupling AQU11-SB has a built-in flow restriction/check valve.

* Flow capacity is measured at 0.4 MPa (4 bar) pressure drop.
