Please contact us directly for more information. The following options are available for special colon orders: A Thread Coated M Bulk Packaging & Thread Coated BP Bulk Packaging, No Thread Coat PSBP Bulk Packaging and HNBR O Rings PSM Thread Coated, Bulk Packaged, and HNBR O Rings V FKM O Ring Material Body (Straights), Tube support, Collet Body (Elbows, Tees) – Brass 'O' Ring – Nitrile Thread Sealant – Precoat 5 Tubing: Tube should be to SAE J844 (Imperial) or DIN 74324 (Metric) Standards and legislation: Fittings and tubing comply to Department of Transport Federal Motor Vehicle Safety Standard, (DOT FMVSS 106) (Mandatory requirements for Inch tube fittings in U.S.A.) Society for Automotive Engineers (SAE) J2494 (Inch tube and fittings) and meet DIN 74324 and German TÜV requirements (Metric tube and fittings) 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 and 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 and 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. Tube Connection/Disconnection 90˚ 90˚ 1. Ensure that the end of the tube is cut square and is free from burrs. 2. Push the tube through the collet into the fitting. 3. Continue pushing the tube through the O-ring until it bottoms on the tube stop. Then pull back on the tube to reinforce the collet teeth gripping action. 4. To disconnect: First ensure there is no air present. Push the tube into the fitting until it bottoms on the tube stop. Then hold down the collet and withdraw the tube.
