PROBLEM TO BE SOLVED: To provide a lightweight joint with a test connection that is resistant to oscillation caused by travel of an air brake mounted vehicle.SOLUTION: A joint 1 with a test connection includes: a test connection part 200; and an air brake piping joint part 100 made of rein and having a cylindrical part 110 to which the test connection part 200 is press fitted and attached. The test connection part 200 includes: a metallic housing 210; an air discharge hole 221; a valve body 220; a valve spring 230; and a packing material 250. In a connected state of a pressure testing machine to the test connection part 200, the valve body 220 is pressed down against energization force of the valve spring 230 so that air in an air passage of the air brake piping joint part 100 is led to the pressure testing machine.SELECTED DRAWING: Figure 1
【課題】軽量で、エアーブレーキ装着車の走行による振動に強いテストコネクション付継手を提供する。【解決手段】テストコネクション付継手1は、テストコネクション部200と、テストコネクション部200が圧入して取付けられる筒状部110を有する樹脂製のエアーブレーキ配管用継手部100とを備え、テストコネクション部200は、金属製のハウジング210と、エアー排出穴221と、弁体220と、弁バネ230と、パッキン材250とを備え、圧力試験用機器のテストコネクション部200への接続状態で、弁体220が弁バネ230の付勢力に抗して押し下げられて、エアーブレーキ配管用継手部100のエアー流路内のエアーを圧力試験用機器へ導くようにした。【選択図】図1
