Product Information

Quick Disconnects – Heavy Duty, Color Coded, F9.381 (Female Coupler)

7250 psi max

Quick Disconnects allow the fluid line to be uncoupled from a machining fixture, automatically sealing the fluid lines on both sides to prevent leakage. Easy one-hand operation without any wrenches or tools. The male Quick Disconnect is usually mounted on the fixture, with the female Quick Disconnect mounted on the hose. To keep Quick Disconnects clean while uncoupled, the female coupling has an available protective plug (order separately below), and the male coupling has an available protective cap.

The color-coded couplings shown here prevent confusion when more than one fluid line must be disconnected. These Quick Disconnects are not only color coded for visual identification, they are also mechanically keyed with a pin to provide positive matching with no chance of confusion. The following colors are available:

Black

White

Red

Yellow

Green

Blue

In standard applications, black is used for the primary pressure line, and white is used for the return line.

Data Sheet

Operation

To couple, push the female coupling's knurled sleeve forward manually, then advance the coupling against spring force until a positive mechanical stop is reached. When the sleeve is released in this forward position, the locking balls of the female section snap into the groove of the male section for positive retention. To uncouple, pull the knurled sleeve back manually. This frees the locking balls and allows the male and female sections to disengage.

Design Considerations & Safety Precautions

Quick Disconnects should only be operated with both sides depressurized. When uncoupling a pressurized pallet fixture after clamping, a Shutoff Valve must be used on the fixture side.
