- Content
- This SAE Standard provides ordering information for any SAE 20R1 through SAE 20R4 hose type (such as EC, HT, LT, or combination thereof.) It is a supplement for Government use but may be used by others.
- Content
- At the request of the military revised the applicable paragraphs and cross reference Table 2 to add wall thickness “S” standard 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 was not wire reinforced so it is equivalent to SAE J20 R1 not SAE J20 R2 (R2 is wire reinforced hose). When the hose suppliers were asked to quote the hoses by DSCC then the error was uncovered.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 equivalent to the old ZZ-H-428 Type 1 standard wall. First column, second paragraph an “S” was added to each SAE-R1 part number.
