Abstract
A connection socket for a tubular press connection including a socket cup having a metal alloy composition and comprising: an O-ring portion defining an O-ring recess; a plurality of gripper arrays positioned equidistant along an internal surface of the socket cup; and a plurality of raised ridges positioned equidistant on an exterior surface of the socket cup. The raised ridges may extend over the gripper arrays.

A connection socket for a tubular press connection, comprising:
- a socket cup having a metal alloy composition and comprising:
- an O-ring portion defining an O-ring recess;
- a plurality of gripper arrays equidistantly spaced around a circumference of an internal surface of the socket cup, wherein each of the plurality of gripper arrays extends axially between an open end of the socket cup and the O-ring portion and is oriented parallel to an adjacent gripper array;
- and
- a plurality of raised ridges equidistantly spaced around a circumference of an exterior surface of the socket cup, wherein the raised ridges are solid projections extending outward from the exterior surface such that a thickness of the socket cup is greater at the plurality of raised ridges.
