Abstract

A sealed joint structure for connecting a tube to a male threaded valve or fitting which allows fluid to be sampled or sounds to be amplified more precisely from a location within a fluid vessel, closer to the moving components. The connection includes a valve, a flared tube, a radial seal and a backup spacer. The present invention relates to a novel fluid transfer connection to draw or fill fluid residing in a remotely accessible reservoir from a tube mounted in a male threaded fitting. This fitting is typically mounted to a port on the reservoir. Typically fluid is drawn to analyze the physical and chemical properties of the fluid especially in oil lubricated power transmission devices such as gearboxes and pumps. It is highly desirable to draw, in a timely fashion, a representative fluid sample from the same location in the reservoir, from time to time, in order to accurately trend changes in fluid characteristics that relate to the integrity of the fluid and the lubricated device.
