Table T24 — Port Detail — SAE J1926-1 (ISO 11926-1)
1)
Nominal tube OD is shown for the standard inch sizes and the conversion to equivalent millimeter sizes. Figures are for
reference only, as any boss can be used for a tubing size depending upon other design criteria.
2)
See SAE J846 for more information.
3)
If face of boss is on a machined surface, dimensions d2 and L3 need not apply as long as corner radius R0.2 is maintained.
4)
Diameter d5 shall be concentric with thread pitch diameter within 0.004 in (0.1mm) FIM, and shall be free from longitudinal and
spiral tool marks. Annular tool marks up to 100 µin (2.5µm) max. shall be permissible.
5)
Tap drill depths given require use of bottoming taps to produce the specified full thread lengths. Where standard taps are
used, the tap drill depths must be increased accordingly.
6)
Maximum recommended spotface depth to permit sufficient wrench grip for proper tightening of the fitting or locknut.
7) 90
durometer nitrile is standard for hydraulic applications.
8)
See page T34.
NOTE:
For port tapping tools, see
pages R32
and
R33.
For assembly torques see
page S5.
