Abstract: A fitting assembly for fluid and vapor connection comprising a first tube, a second tube and a thin strip of polymeric material. A male member is formed at the end of the first tube. A hollow female body is formed at end of the second tube. The male member is received in the female body. The strip of polymeric material has a layer of adhesive applied to one surface of the strip. The strip is bonded to the male member and unbonded to the female body. The strip is compressed between the male member and the female body.

Abstract: A 90° swivel connector capable of rotating 360° has threads on one end that screw into a threaded hole in a boss on a compressor portion of a turbocharger and has barbs on the other end of the swivel connector for receiving and retaining a hose. The 360° rotation enables alignment of the swivel connector with the hose to prevent kinking of the hose when the relative angular position of the connector and hose is varied to facilitate diverse engine usage.

Abstract: A pipe fitting includes a slider disposed in an insertion hole of a main body so as to be axially moved and includes a pressed portion which a falling-off preventing flange of a pipe abuts so that the slider is pressed axially when the pipe is inserted into the insertion hole. A fitting checker includes a pair of spreading legs having respective claws, the fitting checker being detachably attached to the main body so that the legs hold the main body. The claws engage the body and the slider so that the fitting checker is not allowed to be detached from the body when the legs are closed. The legs are spread so as to release the claws from engagement with the body and the slider so that the fitting checker is allowed to be detached from the body. Releasing protrusions are formed to protrude from inside portions of the legs of the fitting checker, the releasing protrusions being pressed so that the legs are elastically deformed in respective opening directions.
