Abstract

This SAE Aerospace Standard (AS) offers gland details for a 0.364 inch (9.246 mm) cross-section gland (nominal 3/8 inch) with proposed gland lengths for compression-type seals with two backup rings over a range of 7 to 21 inches (178 to 533 mm) in diameter. The dash number system used is similar to AS568A. A 600 series has been chosen as a logical extension of AS568A, and the 625 number has been selected for the initial number, since 300 and 400 series in MIL-G-5514 and AS4716 begin with 325 and 425 sizes. Seal configurations and design are not a part of this document. This gland is for use with compression-type seals including, but not limited to, O-rings, T-rings, D-rings, cap seals, etc. Purpose The current O-ring gland design standard, AS4716, specifies gland dimensions for 0.070 to 0.275 inch (1.778 to 6.985 mm) cross-section O-rings. For landing gear and other large diameter applications, a larger cross-section seal has advantages in performance, and longer life. To address this need, this aerospace standard specifies gland dimensions and other pertinent criteria based on O-rings for nominal 3/8 inch (9.53 mm) cross-section glands.
