Mounting Dimensions for O-Seal Connectors
*ALLOW CLEARANCE FOR FULL THREAD
Installation Instruction
In order to prevent the leakage with SUPERLOK O-Seal Fittings, the surface perpendicular to the axis of the thread should be flat. When installing an O-Seal fitting, turn it until finger-tight.(The squeeze on O-Ring can be felt during the last 1/4 turn). After finger-tight installation, snug lightly with a wrench.
When connecting the tubing to the SUPERLOK connector, always use a back-up wrench on the O-Seal fitting hex so it does not turn while the nut is being tightened. Also use a back-up wrench when disconnectiong a tubing connection.
For a raised surface, such as Figure 1, it is recommended that the flat surface have a diameter at least as large as dimension A for the various size O-Seal fittings. This diameter is sufficient to allow metal-to-metal contact outside of the O-Ring sealing diameter and to prevent O-Ring extrusion at high pressure.
Figure 2 is an O-Seal fitting using with a counter bored or recessed hole. In this case, the diameter B is sufficient to allow the round shoulder of the O-seal to clear for proper installation. D gives the maximum depth that can be used with this diameter.
Figure 3 shows the usage at deeper grooved or concaved area and E is the maximum depth that will allow a thin wrench(1/8) to hold the O-Seal fitting while the SUPERLOK connection is made to the tubing. The diameter C is sufficient to allow the hex of the fitting to turn in the recessed hole.

SAE/MS Straight Thread Positionable Elbows and Tees
 
Installation instructions
1. Lubricate O-Ring with the lubricant which is applicable for the system fluid, environment and O-Ring material. (Standard O-Ring materials is viton. Other O-Ring materials are also available).
2. Turn the fittings into the straight thread boss until the metal back- up washer contacts the face of the boss. At this moment, O-Ring gets into inclined groove.
3. Until SUPERLOK's end is oriented in the proper direction, position the fittings by turning to counter clockwise.(no more than 1 turning)
4. Until the washer contacts to the face of the bosses, tighten the fittings with wrench and back-up wrench .
Note: SAE/MS's POSITIONABLE TEE and ELBOWS shall be compatible with SAE J1926, MS16142, or O-Ring female straight thread for JIS boss.
 
SAE/MS Internal Straight Thread Boss
O : This surface would be perpendicular to the thread pitch diameter within 0.010 FIR when measured at “O” diameter.
D : This dimension applies only when tap drill cannot pass through the entire boss.
