Abstract
A high pressure fitting for placing on a tubing includes an annular sleeve having sealing rings therein and a collar enclosing a portion of the sleeve to restrain lateral movements of the sleeve with respect to the tubing. The sleeve has an interior threaded region to receive a plug and an interior annular region. A recess in the annular region retains an O ring and two backup rings which contact the tubing. The sleeve does not contact the tubing. The collar includes two members that have a flange extending into a recess of the exterior of the sleeve to retain the sleeve. The collar also includes an interior tapered annular region spaced away from the end of the tubing for retaining tapered sleeves. The tapered sleeves grip the tubing to prevent movement of the collar and the sleeve with respect to the tubing when high fluid pressure is in the tubing. A tube guide having a shoulder abutting the end of the tubing aids in placing the sleeve on the tubing. The tube guide has a diameter at the shoulder, equal to or slightly greater than, the external diameter of the tubing. The tube guide is placed in the tubing and the sleeve is slid over the tube guide and onto the tubing after which the tube guide is removed.
