Abstract

A pipe fitting includes a tubular member having first and second sockets, each configured to receive an end of a pipe section such that a gap exists between an outer surface of each pipe section and an inner surface of the sockets. A pair of ports extend through the tubular member in each socket and are in fluid communication with each gap. The first socket includes a first annular sealing member that seals the first gap, and the second socket comprises a second annular sealing member that seals the second gap. The annular sealing members may have quad seal structures. A first retaining member may engage the first socket to retain the first annular sealing member at the open end of the first gap, and a second retaining member may engage the second socket to retain the second annular sealing member at the open end of the second gap.

Dependent claims

A pipe fitting, comprising:

a tubular member comprising first and second sockets, wherein the first socket is configured to receive an end of a first pipe section therein such that a first gap exists between an outer surface of the first pipe section and an inner surface of the first socket, wherein the second socket is configured to receive an end of a second pipe section therein such that a second gap exists between an outer surface of the second pipe section and an inner surface of the second socket, wherein the first socket comprises a first annular sealing member that is configured to seal an open end of the first gap, and wherein the second socket comprises a second annular sealing member that is configured to seal an open end of the second gap;
a first pair of ports extending through the tubular member in circumferentially spaced-apart relationship and in fluid communication with the first gap, wherein the first gap is configured to receive a bonding agent via one of the first pair of ports;
a second pair of ports extending through the tubular member in circumferentially spaced-apart relationship and in fluid communication with the second gap, wherein the second gap is configured to receive the bonding agent via one of the second pair of ports;
a first retaining member configured to engage the first socket and retain the first annular sealing member at the open end of the first gap, wherein the first retaining member comprises an opening configured to receive the end of the first pipe section therethrough;
and
a second retaining member configured to engage the second socket and retain the second annular sealing member at the open end of the second gap, wherein the second retaining member comprises an opening configured to receive the end of the second pipe section therethrough.
