Body - The body has an internally machined form to secure the collet(s), “O” ring(s) and
Tube support(s). It also has internal & externally machined thread form(s) for
connection to ports where applicable.
Collet - The purpose of the collet is to grip the tube and ensure it is retained by the fitting
at all times.
“O” Ring - The “O” ring is to ensure adequate interference between the tube & fitting body
therefore providing a pneumatic seal at all times.
Tube Support - The tube support prevents the tube collapsing during extreme tensile loading
conditions. Such conditions are only encountered during performance testing and
far exceed those experienced during normal use.
