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.

CURRENT
AS5798A
This SAE Aerospace Standard (AS) specifies the dimensions, tolerances and size codes (dash numbers) for O-rings with a larger cross-section than those to AS568, for use in glands per MIL-G-5514 where squeeze at low temperature is often insufficient to provide a leak-tight seal.

Aerospace Size Standard for Oversize O-rings

HISTORICAL
AS5798
This SAE Aerospace Standard (AS) is applicable to military and commercial aircraft. It specifies the dimensions, tolerances and size codes (dash numbers) for use in glands per MIL-G-5514 where squeeze at low temperature is often insufficient to provide a leak-tight seal. The dimensions and tolerances specified in this standard are suitable for any elastomeric material. This standard should not be used as a part standard, therefore no part numbers like AS5798-001X shall be created. Each dash number, which should be appended to an appropriate drawing or standard number, identifies one size O-ring only. An AS5798 sized O-ring is intended to replace an AS568 sized O-ring of the same dash number. An X suffix is part of the dash number to signify oversize. Temperature limitations of 275 °F (135 °C) and coefficient of thermal expansion of 9.0 × 10-5 unit length per °F (1.6 × 10-4 unit length per °C) were used for swell calculations.
