  • Method and arrangement for introducing fluorescent dye into a system to be leak tested
    Patent number: 6164348
    Abstract: A method and arrangement for supplying dye to a leak tester and injecting the dye into a sealed system by precharging a disposable plastic syringe with a sufficient volume of dye to conduct the leak testing. The precharged syringe is shipped to the tester who connects the syringe to a hose assembly having a check valve, and a Luer coupling adapter at one end and a Schrader at the other end, which is then connected to the system, and the syringe plunger advanced to inject the dye. An adjustable stop on the syringe plunger allows an accurately set portion of the total volume to be injected.
