Abstract
A high pressure plug/port assembly includes a plug having a head portion at one end, a guide portion at the other end and an O-ring portion therebetween. An annular plug seat surface extends radially inward from the head portion to the O-ring portion at the intersection thereof and a chamfered surface extends radially outward from the O-ring portion to the guide portion at the intersection thereof. The port includes a threaded counterbore in threaded engagement with the plug head portion, a smaller bore receiving the plug's guide portion and a frusto conical bore extending from the smaller bore to the counterbore and defining an annular port seat surface extending radially outward from the frusto conical bore to the counterbore. The seat surfaces provide an undistorting, annular sealing area isolating the threaded connection from high-pressure fluid while the frusto conical bore and plug configuration compresses an O-ring seal in the O-ring portion into sealing engagement with high pressure fluid in the smaller bore.
