Frequently Asked Questions

What is the aerospace standard for O-rings?

The primary aerospace O-ring standard is AS568 (formerly MIL-R-83248), published by SAE International. It defines standard sizes, tolerances, and dimensions for O-rings used in aerospace hydraulic, pneumatic, and fuel systems. MIL-SPEC materials such as MIL-P-5315 and compound specifications like AMS 7276 are also commonly referenced for aerospace applications.
