This SAE Aerospace Recommended Practice (ARP) addresses the general requirements for data recording procedures, packaging, and storing of elastomeric seals and seal assemblies which include an elastomeric element prior to the seal being assembled into hardware components. The requirement for packaging is an integral part of the controlled storage procedure and provides a means of positive product identity from the time of manufacture to the time of assembly into a component.

This SAE Aerospace Standard (AS) specifies standardized gland design criteria and dimensions for static face seals for internal pressure and external pressure applications for aerospace hydraulic and pneumatic applications using the same size range as AS4716 and AS5857 where applicable. Some small diameter sizes are excluded because they are not practical. The glands have been specifically designed for applications using AS568 size elastomeric O-rings with related Class 2 tolerances at nominal system operating pressures up to 3,000 psi (20,680 kPa) utilizing no anti-extrusion (backup) rings. While the gland dimensions herein have been designed for pressures up to 3,000 psi (20,680 kPa) these glands may be used for higher pressures, but extra precautions need to be taken and testing should be performed to ensure integrity of performance.

This SAE Aerospace Standard (AS) specifies standardized gland design criteria and dimensions for static face seals for internal pressure and external pressure applications for aerospace hydraulic and pneumatic applications using the same dash size range as AS4716 and AS5857 where applicable.

This SAE Aerospace Information Report (AIR) contains a description of the design approach, the calculations, some comparisons to alternate SAE Aerospace Recommended Practice (ARP) documents, and the background information used to generate the standard face seal gland dimensions specified in AS6235. NOTE: This AIR should be read in conjunction with AS6235. In some instances, the information contained within AS6235 is repeated for clarity.
