5、 Aerospace Size Standard for O-rings RATIONALEThe drawing has been revised to eliminate the parting line projection shown in earlier issues since it is not applicable to an O-ring size standard. 1. SCOPE 1.1 Purpose This SAE Aerospace Standard (AS) specifies the inside diameters, cross-sections, tol

6、erances, and size identificationcodes (dash numbers) for O-rings used in sealing applications and for straight thread tube fitting boss gaskets. The dimensions and tolerances specified in this standard are suitable for any elastomeric material provided that suitable tooling is available. 1.2 Applica

7、tion 1.2.1 This standard is intended to be used in the preparation of Company, Military, or other Standard Drawings for O-rings. Each dash number, which should be appended to an appropriate Drawing or Standard number, identifies one nominal size O-ring only. 1.2.2 No attempt is made in this AS to in

8、dicate which of the O-ring sizes listed under this system should be included in any particular Standard Drawing. Its only purpose is to standardize O-ring sizes and dimensional tolerances and the means of identifying them dimensionally. 2. REFERENCES There are no referenced publications specified he

9、rein. 3. NOTES 3.1 In Table 1, the dash numbers are divided into groups of one hundred, and within each group are sequential and non-significant. Each hundred group, however, identifies the cross section size of the O-rings within the group. For example, all 0.070 inch (1.78 mm) and smaller O-ring c

10、ross sections fall into the group of -001 thru -099. The 0.103 inch (2.62 mm) cross section rings fall into the group of -100 thru -199, and so on. SAE INTERNATIONAL AS568D Page 2 of 15 3.2 Table 2, using the 900 series dash numbers, lists all of the presently standardized straight thread tube fitti

11、ng boss gaskets. This series has traditionally utilized the significant dash numbering system, wherein the dash number designates the tube size in 16ths of an inch. This practice is also followed here, with the exception of the -901, which is intended for a 0.0938 inch (2.38 mm) nominal OD (outside

12、diameter) tube, the 0.0625 inch (1.59 mm) OD tube not being in common aircraft use. 3.3 In the interest of standardization, it is requested that companies or agencies do not use the dash numbers in Table 1 to which sizes have not been assigned. Sizes not assigned are indicated by an asterisk (*). An

13、yone feeling that any special size not now shown is widely enough used to justify standardization should direct such a request to SAE A-6 Committee for coordination. 3.4 Figure 1 illustrates that all diameters of the cross-section should be equal.
