Elastomer Compatibility Considerations Relative to Elastomer Selection

CURRENT
AIR786C
This SAE Aerospace Information Report (AIR) contains data relative to the chemical nature of aerospace fluids and relates each to its empirical effect upon elastomeric components. Since the compatibilities of elastomers are determined by the compounding as well as the nature of the base polymer, the elastomers considered are limited to finished compounds for which material or performance specifications can be referenced.

AS4716
This SAE Aerospace Standard 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 at pressures exceeding 1500 psi utilizing one or two anti-extrusion (backup) rings and applications at pressures under 1500 psi 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 specifically designed for standard size O-rings, these glands are also to be used with other elastomeric seals.

AS4716B
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 (10.34 MPa) utilizing one or two anti-extrusion (backup) rings and applications at pressures below 1500 psi (10.34 MPa) 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.

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.
