Tube Flaring Dimensions – 37º JIC and 45º SAE |
RYCO S6, S6M, S6S and SA6 Tube Nuts and Sleeves are for use with flared steel hydraulic tubing. Dimensions for flares shown below are as specified in SAE J533 “Flares for Tubing”.
Tubing must be flared to the correct dimensions. Flares must be free from loose scale, burrs, slivers, and cracks.
Seating surfaces must be smooth and free from nicks, pit marks, and any other defects that prevent sealing.
The flare seat must be concentric with the tube outside diameter within 0,38 mm (.015”) Full Indicator Reading (FIR).
Smoothly breaking (radiusing) the outside corner of the tube prior to single flaring, to minimise splitting, is permissible.
For S6, S6S and SA6 for Imperial Outside Diameter Tubing, use only seamless annealed hydraulic tubing to ASTM A179 of wall thickness no greater than that specified in the tables.
For S6M for Metric Outside Diameter Tubing, use only seamless annealed hydraulic tubing of wall thickness no greater than that specified in the tables.
Tubing may be double flared for thin wall thicknesses, or single flared for thicker walled tubing. Dimensions below are for single flared tubing.
Recommended maximum wall thickness of tubing specified in tables is the thickest tubing normally considered suitable for flaring. Optional configurations to provide extended length of seal contact surface for tube wall thickness exceeding the limits in the tables, are also specified in SAE J533.
