SAE International
Publication Date:
Jan 1, 1993
Scope:
1. 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. (See Figures 1 and 2.)
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. 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 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.
Flanged heads shall be as specified in Figure 3 and Table 1. Split
flange clamp halves shall be as specified in Figure 4 and Table 1. Port
dimensions and spacing shall be as specified in Figure 5 and Table 2.
O-ring seals, having nominal dimensions as indicated in Table 1, are
used in conjunction with these connections. They shall conform to the
seals specified in SAE J120, Table on Dimensions and Tolerances.
Bolts for use with these connections shall be of the sizes and lengths
indicated in Table 1. They shall be of SAE Grade 5 material or better
as specified in SAE J429. 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
