A fluid quick connector in cartridge form carrying a shut off valve is mountable in a bore in a fluid charged use device. An end form retainer is mounted in the cartridge for locking an end form in a bore in the cartridge. The shut off valve is internally mounted within the cartridge to selectively open and close a flow path through the cartridge from the fluid use device to the end form.

Fluid shut off valve cartridge with quick connection

A quick connector includes a male component in the form of a spool fixedly mounted to a fluid conduit and a female component in the form of a housing having a bore open at one end for receiving the male component therein. A latch is rotatably mountable on the spool and is movable relative to a transverse channel in the female component between a first installed position with respect to the channel and a second latched position wherein the latch engages opposed notches in the channel to latch the spool in the housing. At least one latch clip is mountable on the latch and engageable with edges of the channel in the body to resist rotation of the latch from the latched position. An optional secondary latch clip is engageable with the latch clip, the latch and the opposed side edges of the channel to further resist rotation of the latch from the latched position.

Twist lock high pressure quick connector

A quick connect body having first, second and third ports carries an insert extending from the first port to the third port and forming first and second flow paths through the body from the first and second ports, respectively, to concentrically mounted conduits attached to the third port and to one end of the insert. Retainer elements are mounted on the body and/or the insert to sealingly couple first and second conduits to the body and the insert.

Coaxial quick connector

A connection between a fluid conduit and an air flow port mounted on an air flow device includes a housing having a through bore which receives a flange on an end form of the conduit. One end of the port is disposed in the bore in the housing in sealed engagement with the end form. A transverse bore in the housing receives a retainer to lock the port in the housing preventing axial separation of the port from the conduit.

Air flow conduit quick connector

A quick connector for connecting fluid lines includes a first connector having a housing for receiving a spool carrying conduit. The spool sealingly engages an endform on the conduit. At least one seal element and a retainer ring are pre-mounted in a bore in the housing and engage the spool to form a seal between the inner surface of the bore in the housing and the spool and to retain the spool in a fully inserted position in the housing. A method of assembling the quick connector is disclosed in which a stuffer pin is preassembled with the retainer ring mounted at a compressed diameter within a retaining collar on one end of the stuffer pin and the seal element mounted the stuffer pin. The stuffer pin is inserted into the bore in the housing until the seal element snaps into one groove in the bore and the retainer ring engages another groove in the bore in the housing. The stuffer pin is removed and a spool having a tapered end portion is slid through the retainer ring causing the tapered portion to expand the retaining ring outward until the retaining ring snaps behind an end shoulder on the spool. A centering collar carried on one of the spool engages an inner surface of the retaining ring to concentrically center the retaining ring with respect to a longitudinal axis through the tube and spool.

High pressure quick connector

A nozzle for a vehicle window washing system includes a stem releasibly attachable through an aperture in a vehicle panel. A through bore extends through the stem and receives a spring biased check ball. Ribs project inward into the bore for supporting the spring and for forming fluid flow paths exteriorly of the spring through the stem. A head having a fluid discharge bore is snap connected to the stem via a mating projection and recess. A flange projects intermediately between the ends of the stem and seats on a vehicle panel to isolate the snap connection between the head and the stem from the mounting connection between the stem and the vehicle panel. A secondary connection is provided by a plurality of projections extending outward from the flange into recesses in a peripheral side wall of the head. A seal is mounted between the stem and the head.
