ELASTOMER COMPATIBILITY CONSIDERATIONS RELATIVE TO O-RING AND SEALANT SELECTION

1972-04-18
HISTORICAL
AIR786A
This document contains data relative to the chemical nature of aerospace fluids and relates each to its 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 could 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.

AS4716A
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.

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.

Face Seal Gland Design, Static, O-ring and Other Seals for Aerospace Hydraulic and Pneumatic Applications

CURRENT
AS6235A
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.
