Abstract: A quick disconnect coupling which includes a tubular male plug defining a groove in the exterior surface thereof. The plug is received in a socket which defines apertures on its opposite sides. These apertures are aligned with the groove in the plug when the plug is sealingly seated in the socket. Two lever arms are pivotally connected to opposite sides of the socket. Each has an elongated handle portion, and a pivot head pivotally connected to said socket adjacent one of the apertures. A cam portion on each pivot head projects through the adjacent socket aperture into camming engagement with the groove. Two pairs of lugs are mounted on opposite sides of the socket with each pair defining aligned pin holes. The lugs in each pair are positioned on opposite sides of one of the handles when the lever arms are in their locking positions. A locking pin is provided having a first straight leg extending through the aligned lug pin holes, and further having a bent angulated leg of generally W-shaped configuration.

Abstract: A fluid handling body and a method of attaching extension tubes to the fluid handling body which effectively seals the tubes to the body in a simple manufacturing operation, reducing the number of manufacturing operations required while minimizing the possibilities of damage to the tubes or undesirably restricting the fluid flow path in the body or tubes. The method hereof is particularly advantageous where several tubes are to be attached to the body to produce a precise, leak-free component. The body includes a fluid flow passageway extending into one end and a saucer-like cavity in the other end. A plurality of bores extend through the body between the cavity and passageway. With the tubes received in the bores, a paste is applied in the cavity. The outer periphery of the body is heated, melting the paste in a single heating operation and effecting flow of the paste in the cavity into circumscribing relation about the tubes.
