24、rd and “H” heavy wall.An error was made in the cross-reference from ZZ-H-428 to SAE J20 hose. ZZ-H-428 Type 1 hose wasnot wire reinforced so it is equivalent to SAE J20 R1 not SAE J20 R2 (R2 is wire reinforced hose). Whenthe hose suppliers were asked to quote the hoses by DSCC then the error was unc

25、overed.Another error was found in the first column, 5th SAE number ends in an “N” and should end in an “H”.There was no SAE J20 “N” callout.SAE J20R1 hose has two thicknesses “S” = standard and “H” = heavy wall so the part number cross-reference must indicate which wall thickness to purchase as the

26、equivalent to the old ZZ-H-428 Type 1standard wall. First column, second paragraph an “S” was added to each SAE-R1 part number.Relationship of SAE Standard to ISO StandardNot applicable.ApplicationThis SAE Standard provides ordering information for any SAE 20R1 through SAE 20R4 hosetype (such as EC,
