O Ring Straight Thread Connector (SOSC)

O-Ring Connector by SuperlokUSA® – High-Performance Sealing for Critical Systems

The O-ring connector by SuperlokUSA® provides exceptional sealing performance in hydraulic, pneumatic, and industrial fluid transfer systems. Engineered with a dual-seal mechanism, it features an elastomeric O-ring for primary sealing and a metal-to-metal backup for added reliability. This makes it ideal for applications where zero-leak performance is required, such as industrial automation, aerospace, and fluid power systems.

With a pressure rating of up to 6,000 psi and a temperature range of -65°F to 400°F, these connectors excel in high-vibration environments and systems experiencing constant pressure fluctuations. Available in 316 stainless steel and brass, SuperlokUSA® O-ring connectors offer multiple sealing options, including Viton, Buna-N, and PTFE O-rings, to ensure compatibility with a wide range of fluids and gases.

Compared to traditional compression fittings, O-ring connectors by SuperlokUSA® reduce assembly time while enhancing sealing reliability, making them the preferred choice for precision-driven industries that require long-lasting, leak-proof performance.

Mounting For O Seal Connector

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.
