5、ard for Oversize O-rings RATIONALEAS5798 has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE 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-
6、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 creat
7、ed. 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 limitatio
8、ns of 275 F (135 C) and coefficient of thermal expansion of 9.0 x 10-5unit length per F (1.6 x 10-4unit length per C) were used for swell calculations. Applications that exceed these values should be evaluated for excessive gland fill. 2. REFERENCES The following publications are provided for inform
