MAP3440A O-Ring Groove Design for Metric O-Ring Seals Used in Static Radial Compression Applications Specifically for Engine and Engine Control Systems

This SAE Recommended Practice provides the design criteria for static elastomeric O-ring seals used specifically in engine and engine control systems. It provides radial compression groove dimensions for aerospace metric O-ring sizes specified in MA2010. The conditions considered to formulate the design criteria are also described, e.g., seal stretch, cross-section reduction, seal squeeze, and swell.
