AEROSPACE STANDARD, GLAND DESIGN, O-RING AND OTHER ELASTOMERIC SEALS

1993-06-11
HISTORICAL
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.

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.

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

2015-12-19
HISTORICAL
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.

Gland Design, Computation of Seal Squeeze and Gland Volume

CURRENT
ARP4727B
This SAE Aerospace Recommended Practice (ARP) presents two BASIC language computer programs to promote and standardize the computation of installed O-ring cross-section deflection hereafter referred to as "squeeze" and the computation of gland volume. The two programs were written with line numbers and without use of any system specific BASIC commands to allow usage with as many systems as possible with a minimum of editing. The programs support entry of customary U.S. or metric dimensions.

AS5857
This SAE Aerospace Standard (AS) provides standardized gland (groove) design criteria and dimensions for elastomeric seal glands for static applications. The glands have been specifically designed for applications using SAE AS568 size O-rings at pressures exceeding 1500 psi (10.3 MPa) utilizing one or two anti-extrusion (backup) rings and applications at pressures under 1500 psi (10.3 MPa) without backup rings. The glands have been sized to provide increased squeeze as compared to AS4716 for more effective sealing at low temperatures and low seal swell conditions. These glands are not recommended for dynamic use. Primary usage is for static external sealing. The rod dimensions are the same as AS4716. The cylinder bore dimensions are the same as AS4716 except for sizes -001 thru -011 and -104 thru -113.
