Abstract

A hydraulic chuck device for testing the integrity of a ferrule sealed to a tube proximate one end of the tube. The device includes a chuck body having an inlet end with an internal collet engaging surface and a second end. Collets are mounted inside the inlet end of the body. The collet has faces shaped to conform to a ferrule on a tube, and normally urges the collets against the engaging surface of the body. An actuator is connected to a source of fluid, and is mounted in the body. The actuator includes a ferrule seal which is normally in a ferrule engaging position for introducing the fluid to the tube. A handle is provided for inserting a ferrule and tube into the device to allow the collets to engage the ferrule on one side of its seal to the tube and the ferrule seal to engage the ferrule on the other side of its seal to the tube when fluid is introduced into the tube.
