1/ This table is referenced from SAE-J517 100R10 which is
discontinued by SAE, therefore see table VIII.
2/ Dimensions are in inches.
3/ Metric equivalents are given for information only.
Hose assembly code number. The purpose of this slash sheet is to provide hose assembly code
numbers for determining the hose diameter, fitting X, fitting Y, and bend angles (when applicable) as
shown in tables II through VI. The bend angles are called "style codes" and consist of hose assembly
styles as specified in MIL-DTL-52471.
