Scope--This SAE Standard covers complete general and dimensional specifications for the flanged heads and split flange clamp halves applicable to four-bolt split flange type tube, pipe, and hose connections with appropriate references to the O-ring seals and attaching components used in their assembly. Bolts for use with these connections shall be of the sizes and lengths indicated in Table 1. The following general China Carriage Bolts Manufacturers specifications supplement the dimensional data contained in Table 1 with respect to all unspecified detail.. The values stated in SI units are to be regarded as the standard. Port dimensions and spacing shall be as specified in Figure 5 and Table 2. Flanged heads shall be as specified in Figure 3 and Table 1. The values given in parentheses are for information only.

This specification covers the pipe material and wall thickness applicable to lap joint flange pipe ends, manufactured by a mechanical forming process.) Also included are recommended port dimensions and port design considerations. The flanged heads specified are incorporated into fittings having suitable means for attachment of tubes, pipes, or hoses to provide connection ends. (See Figures 1 and 2. THE RATED WORKING PRESSURE OF A HOSE ASSEMBLY COMPRISING SAE J518 HOSE CONNECTIONS AND SAE J517 HOSE SHALL NOT EXCEED THE LOWER OF THE TWO WORKING PRESSURE RATED VALUES. Consumers should consult with suppliers concerning lists of stock production prevailing-torque hex and hex flange nuts.

They shall conform to the seals specified in SAE J120, Table on Dimensions and Tolerances. Socket head cap screws of SAE Grade 5 material or better are acceptable. Lock washers, if used, shall be in accordance with the light spring lock washers specified in SAE J489, Dimensions of Light, Medium, Heavy, Extra Heavy, and Hi Collar Spring Lock Washers, and of sizes applicable to the corresponding bolts. They shall be of SAE Grade 5 material or better as specified in SAE J429. The inclusion of dimensional data in this Standard is not intended to imply that all of the nut sizes in conjunction with the various options described herein are stock items. O-ring seals, having nominal dimensions as indicated in Table 1, are used in conjunction with these connections.

This Standard covers the complete general, dimensional, mechanical, and performance data for metric prevailing-torque hex nuts and hex flange nuts of property classes 5, 9, and 10 as defined in ASTM A563M. These connections are intended for application in hydraulic systems, on industrial and commercial products, where it is desired to avoid the use of threaded connections. The lap joint flange connection has been widely used for low-pressure systems in the marine, process piping, and similar industries. Split flange clamp halves shall be as specified in Figure 4 and Table 1
