Installation Instruction
In order to prevent 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 disconnecting 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.
