SCOPE 1.1 Scope This SAE Aerospace Standard (AS) establishes the re

21、quirements for 24 degree cone flareless fluid connection fittings and nuts, internally or externally swaged, preset, or welded sleeves for use in aircraft fluid systems at nominal operating pressures up to and including 3000 psi. 1.2 Classification Fittings shall be furnished in the types and styles

22、 designated by the applicable AS, MS, NAS standard drawings. This specification includes the requirements for flareless fittings used with externally preset bite type sleeves and also for machined acorn fitting ends such as NAS1760, AS4458, and AS4703. It is intended to serve as a procurement specif

23、ication for the fittings described herein and in Section 6. The requirements for externally preset bite type sleeves are given in AS18280/1. The requirements for swaged or welded sleeves and tube ends are given in AS18280/2. 2. REFERENCES 2.1 Applicable Documents The following publications form a pa
