6、00R10 hoses have been discontinued by SAE. Suggested SAE-J517 replacement hoses are specified in table I. The “RE” designator at the end of the hose type “100RE” is a MIL-DTL-52471 term used to indicate a hose type that has been discontinued and to use an SAE-J517 replacement hose see MIL-DTL-52471/
7、3. The hose assembly document MIL-DTL-52471/3 is being retained so replacement parts can be ordered from this slash sheet. The intent is to allow users the ability to use PINs in MIL-DTL-52471/3 to order hose assemblies. Manufacturers will use the appropriate substitute hose and fittings to make a h
8、ose assembly to meet the mating requirements of the fittings listed in this slash sheet, and shall meet the performance requirements of SAE-J517, and mark it in accordance with MIL-DTL-52471/3.
