This recommended practice provides the design criteria for static elastomeric O-ring seal applications, radial squeeze groove dimensions for aerospace metric O-ring seal sizes as specified in MA2010. The conditions considered to formulate the design criteria are also described, e.g., seal stretch, cross-section reduction, squeeze, and swell.

This recommended practice provides the design criteria for static elastomeric O-ring seal applications, axial compression (face type) 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 squeeze and groove volume to accommodate O-ring swell.

This SAE Metric Aerospace Standard (MA) defines the requirements for heavy-duty polytetrafluoroethylene (PTFE) lined, para-aramid reinforced, hose assembly suitable for use in 135 °C, 34,500 kPa, aircraft and missile hydraulic fluid systems.

This procurement specification covers aircraft quality metallic gaskets having a "C" shape cross-section to form a seal ring, made from a corrosion and heat resistant age hardenable nickel base alloy of the type identified under the Unified Numbering System as N07750.
