Abstract
A quick-coupling union for oil and gas tubular members that provides a more stable joint connection, a redundant seal arrangement, and a method for pressure testing the seals. The union and sealing arrangement includes an elongated tubular receiving member, further including a central longitudinal cavity therein for receiving an elongated tubular insertion member and an external port in communication with the cavity, at least two sealing members located within the cavity defined by the insertion and receiving members and the dual seals being capable of providing a positive seal between the insertion member and the receiving member the union, further including a nut slidable upon the insertion member for threadably locking the insertion member relative to the receiving member, the sealing members being spaced apart in a manner whereby the external port is interposed between the dual sealing members when the union is fully engaged, thus defining a means for applying a pressure there upon.
