This recommended practice provides the design criteria for static elastomeric O-Ring seals used specifically for engine and engine control systems. It provides axial compression (face type) groove dimensions for aerospace metric O-Rings sizes specified in MA2010. The conditions considered to formulate the design criteria are also described, e.g., seal squeeze and groove volume to accommodate O-Ring volume swell.
Rationale: This standard has been updated to include technical and editorial changes.
Note: This standard was transferred from the E25 General Standards for Aerospace and Propulsion Systems Committee to A6C Seals Committee.
