A pipe joint for joining a pair of adjacent pipe ends includes an improved gasket contruction. An annular radially outwardly extending flange is provided on the periphery of each pipe adjacent and spaced from the pipe end, a cylindrical coupling member is provided including at least one axial slit in the cylindrical wall thereof and a pair of annular arcuate grooves extending outwardly from the interior of the coupling member, the grooves being shaped so as to form an enclosed annular space between each flange and each arcuate groove, and a gasket for sealing the pipe joint having a pair of spaced apart O-rings shaped to be fitted over the pipe ends and compressed within the annular spaces, a connecting web extending between and joining the O-rings along only a portion of their circumferences, and a shield attached to the inner surface of the connecting web for protecting the web from the pipe ends. The connecting web is positioned under the axial slit in the coupling member. The connecting web is particularly shaped so as to form an evenly compressed, tightly sealing gasket when the pipe joint is assembled.

A gasket for forming a seal between two adjacent pipe ends and a coupling spanning the two pipe ends, comprising: a pair of spaced apart O-rings joined along a portion of their respective annular bodies by a connecting member; said connecting member comprising a web of flexible material defining parallel sides, each of said sides being bonded along its length to one of said O-rings, a pair of elevated cross ridges extending between said O-rings at opposite ends of said connecting member, and a depressed central portion bounded by said O-rings and said elevated cross ridges.
