These formulae shall be used to determine drop dimensions for simple bend tube fittings utilizing flare and flareless end connection designs from 0° to 90° used in aircraft and aerospace applications. Individual design standards shall specify parameters, such as centerline bend radius (R), straight tangent length to accommodate bending equipment (X1 and X2), and nut to be used.
This SAE Aerospace Recommended Practice (ARP) establishes the procedure for creating titles of G-3 Committee documents which will be published by the SAE Aerospace Organization. This standardization will avoid several different names describing the same item and will improve alphabetical listings of documents by subject.
This SAE Aerospace Recommended Practice (ARP) is intended to interpret and clarify engineering drawing requirements relating to the manufacture and inspection of fluid system couplings, tube fittings, and hose ends. Because it is impractical to define every minute detail of the part on the face of the drawing, this document describes interpretations of dimensioning of general machining features and otherwise undefined tolerances that fall under the heading of "good shop practice". This document serves as a supplement to engineering drawings when referenced on applicable documents.
This SAE Aerospace Recommended Practice (ARP) establishes the guidelines for selection of titles of aerospace fitting documents generated by SAE Subcommittee G-3B.
