5 FITTINGS For further information www.norgren.com FIT-60 Simple tube connection and disconnection - no tools required Fewer component parts - Internally machined form in body to secure collet reduces number of potential leak paths Corrosion resistant Easy identification - All collets marked with tube size Total fittings system solution Reduced assembly & maintenance times provide time/labor savings Greater reliability and reduced testing Ease of tube insertion in areas of restricted access Tube Connection / Disconnection 90˚ 90˚ Component Functions O RING BODY TUBE STOP COLLET TUBE SUPPORT O RING BODY TUBE STOP COLLET TUBE SUPPORT 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.
