This SAE Aerospace Recommended Practice (ARP) presents a recommended part numbering scheme for fluid system
component parts, which may require complex standard numbers. Standardizing on certain numbering systems provides
for numbering simplicity, ease of interchangeability and supersession (when required), standardization and limitation of
usable codes.
This ARP is similar to ISO/TC20/SC10 and its usage is recommended for commonality in international standard part
numbering practices.
1.1 Purpose
The purpose of this ARP is to consider the part numbering system for hose assemblies, fittings, and clamps. Other
components may be added later.
1.1.1 Each component type has established standard codes, which are unique to that type and cannot be interchanged
with other component types.
1.1.2 The recommendations shown herein are based on the inch system of measurement. Recommendations based
on the metric system of measurement are in coordination in
ISO/TC20/SC10.
1.1.3 Use of these codes is expected, but is not obligatory, when defining characteristics of components covered by
this practice. Codes, other than those specified in this practice, that appear on existing standards may continue to
be used and are not necessarily considered to be in contradiction with this practice.strRefField
