3000 psi Self-Sealing Quick Disconnect/3200 Series*For hydraulic applications ... Meets requirements of MIL-C-25427A

FOR TYPE II (-650 F TO +275° F) SYSTEMS The Aeroquip 3200 Series Self-Sealing Coupling is areliable quick disconnect for 3000 psi aircraft andmissile applications.

Quick Connecting .. . Easily connects with one_.~ = ,_-~ hand; disconnects with a straight pull on the

Union Nut.

Positive Action .. . Valves open simultaneouslywith the locking action. There is no stable in-termediate position where the coupling is par-tially open and unlocked.

No Fluid Loss . . . during connection or discon-nection.

Excludes Air, Dirt, Moisture ... No cavity to trapair, dirt, or moisture.

Simple Construction . . . only thirteen parts plus"0"1 rings and Teflon back-up rings. No deli-

_ - cate mechanisms to malfunction.

Disconnected Coupling with valves <closed. Note how "0" rings provide Ln-exposed and fully protected seal forpoppet and tubular valve sleeve. When K
