Scope:

This SAE Aerospace Standard (AS) provides standardized gland (groove) design criteria and dimensions for elastomeric seal glands for static and dynamic applications. The glands have been specifically designed for applications using SAE AS568 size O-rings, with related class 2 tolerances, at pressures exceeding 1500 psi (10,342 kPa) utilizing one or two anti-extrusion (backup) rings and applications at pressures under 1500 psi (10,342 kPa) without backup rings. The glands have been sized to provide sufficient squeeze for effective sealing while at the same time limiting squeeze to allow satisfactory operation in dynamic applications. While this specification covers the basic design criteria and recommendations for use with standard size O-rings, these glands are also suitable for use with other elastomeric, and polytetrafluoroethylene (PTFE) based seals and packings.
