Abstract
A compression pressure indicator includes a compression member which is disposed within a termination and is constructed such that when exposed to a pressure above a predetermined pressure a portion of the compression member protrudes from the termination thus indicating that optimum pressure has been applied inside the termination. The compression member includes an indicator portion and a collapsible portion, the collapsible portion being shaped such that when exposed to a pressure above the predetermined pressure, the collapsible portion collapses thus allowing relative movement between the indicator portion and pressure extending member such that the indicator portion protrudes a predetermined distance from an end of the pressure exerting member.
