Abstract

A coupling for coupling a first pipe member to a second pipe member each having plain ends. The coupling includes a housing having at least one chamber, a sealing member disposed in the housing, and a plurality of gripping element for engaging the plain ends of the first and second pipe members. A preferred gripping element preferably defines a length to width ratio ranging between about 1.7 and about 3.5 and further preferably defines a pipe engagement surface slope of zero that results in a desired coupling performance. When the coupling is installed in a hydrostatic test piping assembly, the coupling can maintain a hydrostatic pressure of at least 600 PSIG for a period of at least five minutes. Moreover, the coupling can maintain a fluid tight seal between the first and second pipe when exposed to a hydrostatic pressure of up to 900 PSIG.
