Description / Abstract:
Purpose
This SAE Aerospace Standard (AS) specifies the inside diameters,
cross-sections, tolerances, and size identification codes (dash
numbers) for O-rings used in sealing applications and for straight
thread tube fitting boss gaskets. The dimensions and tolerances
specified in this standard are suitable for any elastomeric
material provided that suitable tooling is available.
Application
This standard is intended to be used in the preparation of
Company, Military, or other Standard Drawings for O-rings. Each
dash number, which should be appended to an appropriate Drawing or
Standard number, identifies one nominal size O-ring only.
No attempt is made in this AS to indicate which of the O-ring
sizes listed under this system should be included in any particular
Standard Drawing. Its only purpose is to standardize O-ring sizes
and dimensional tolerances and the means of identifying them
dimensionally
