Gland Design: Nominal 3/8 in Cross Section for Custom Compression Type
Seals
Description / Abstract:
This SAE Aerospace Standard (AS) offers gland details for a
0.364 cross section gland (nominal 3/8 in) with proposed gland
lengths for compression type seals with two backup rings over a
range of 8 to 20 in in diameter.
A dash number system is proposed similar to AS568A.A 600 series has been chosen as a logical extension of AS568A and the 625 number has been arbitrarily chosen for the initial number. (Both 300 and 400 series begin with 325 and 425 sizes.)
Seal configurations and design are not a part of this document. This gland is for use with custom compression type seals including, but not limited to, O-rings, T-rings, D-rings, etc.
Purpose:
The current O-ring gland design standard, MIL-G-5514F, specifies gland dimensions for 0.070 to 0.275 in cross section O-rings (see Figure 1). For landing gear and other large diameter applications a larger cross section seal has advantages in performance and longer life.
