Abstract
A pressure indicator: a body having a pressure chamber which has an inlet for communication with a fluid; a resilient diaphragm having a periphery sealed against the body and having one side thereof exposed to the fluid within the chamber; an indicating arm having an inner end which is integrally formed with the other side of the diaphragm and an outer end arm which is adjacent to a scale, the arrangement being such that pressure of the fluid within the chamber causes resilient deformation of the diaphragm which in turn causes the outer end of the arm to move relative to the scale thereby indicating the pressure of the fluid in the chamber.
