Standard wall thickness hose is 4.3 mm to 5.6 mm wall. Heavy Wall Thickness hose is 5.8 to 7.1 mm wall. The part number code for standard wall is “S” and for heavy wall is “H”. See part numbering example in 4.1. 3.5 Bulk Hose—Bulk hose shall be furnished in lengths of 3.66, 7.62, or 12.19 m (12, 25, or 40 ft, respectively) or in multiples thereof, except that on such orders up to 10% may be furnished in random lengths over 4.57 m (15ft). An additional 10% may be furnished in random lengths over 915 mm (36 in). 3.6 Markings for U.S. Government use only—For U.S. Government use only, marking shall consist of the following: a. Part Identification Number (see 4.2) b. Manufacturer’s Identification code (CAGE) or trademark symbol c. Month and year of manufacture 3.6.1 If there is insufficient space on the hose for the required marking due to small ID hose or too short a straight length, a label carrying the required information shall be taped around the individual pieces of hose in lieu of the standard method of marking. 3.6.2 Marking for non-Government users shall be agreed upon by the customer and manufacturer. 4. Notes 4.1 Part Identification Number—Part numbers shall be constructed as indicated in Figure 1. FIGURE 1—PART IDENTIFICATION NUMBER EXAMPLE—SAE-20R1LTH-A-51X280 indicates a hose with low temperature characteristics, heavy wall, in a Class A compound that is nominally 51 by 280 mm (50.8 mm (2.00 in) ID by 279.4mm (11.00 in) length.) 4.2 Government Specification Replacement—This document is a replacement for Military Drawing MS52130, “Hose, Nonmetallic: Straight, Engine Coolant” and portions of Federal Specification ZZ-H-428, “Hose; Non-Metallic and Hose; Preformed: (for Coolant Systems of Automotive and Other Liquid-Cooled Engines.)” 4.3 Cross Reference Information—Table 2 shows the relationship between designations in this document and ZZ-H-428. MS52130 provided part numbers for ZZ-H-428, Types I through IV hose. SAE J20-1 Revised JUN2002 -4- 4.4 Key Words—Automotive, coolant hose, flexible hose, heater hose, preformed hose, wire reinforced hose. 4.5 Marginal Indicia—The change bar (l) located in the left margin is for the convenience of the user in locating areas where technical revisions have been made to the previous issue of the report.

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. Relationship of SAE Standard to ISO Standard—Not applicable. Application—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.
