AQ - Quick couplings

• Insert and screw type couplings.
• Interchangeable with many other brands on the market.

All quick couplings from NIKE have a check valve and are all supplied with seals and protection caps made of metal or plastic (see table below for specifications). Dust caps made of metal have a longer life time than plastic ones. Protection caps prevent contamination of the hydraulic system. Screw type couplings permit a higher flow rate than insert type ones.

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 rate at 0,4 MPa(4 bar) pressure drop.
