Device and method for connecting a fluid conduit to a receiving fitting

摘要

A fitting provides a means of making a union between a tube and a female fitting with low dead volume and without the use of tools. The fitting is comprised of a tube member that is pressed into the female fitting to automatically remove dead volume. The tube member is pressed into the fitting by a spring with the appropriate tension to hold the tube member against the expected pressure. The fitting also is comprised of a two piece nut assembly. The forward nut compresses a ferrule to create the high-pressure seal. The rearward nut is attached to the forward nut and provides compression and a holding means for the spring.
