Stainless Steel Rapid Screw Elbow Fittings RPL-SF, RPL-S & RPL-G-S Series

90° Routing for Compact Pneumatic Connections

The RPL-SF, RPL-S and RPL-G-S Series Stainless Steel Rapid Screw Fittings are developed for pneumatic installations where tubing needs to change direction without creating a large routing radius. Their 90° elbow structures allow tubing to be guided neatly around valves, cylinders, manifolds, and machine frames, making them especially useful where installation space is limited.

The three configurations provide different connection solutions. The RPL-SF Series Rapid Screw 90° Elbow offers a fixed 90° connection for conventional pneumatic layouts. The RPL-S Series Rapid Screw Rotatable 90° Elbow allows the connected tube direction to be adjusted after installation, providing greater flexibility when routing tubing around equipment. The RPL-G-S Series Rapid Screw Rotatable 90° Elbow With O-ring combines the rotatable structure with an additional O-ring sealing element for improved threaded connection sealing.

Stainless Steel Construction for Demanding Environments

These rapid screw pneumatic fittings are available in 303, 304, 316, and 316L stainless steel. Different stainless steel grades allow the fitting to be selected according to corrosion resistance, mechanical requirements, and operating environment.

Most components are manufactured using automated equipment, with specialized inspectors checking critical production processes to maintain dimensional accuracy and required tolerances.

● Common characteristics:

• 303, 304, 316, and 316L stainless steel options.

• BSP, PT, NPT, and metric thread standards.

• OEM and ODM customization supported.

• CAD drawings available according to customer requirements.

• Ultrasonic inspection and cleaning, followed by drying before shipment.

• ISO9001, CE, and FDA certifications.

Three Elbow Configurations for Different Installation Needs

The differences between the three series allow engineers to select the appropriate structure according to the required connection and tubing orientation:

• RPL-SF Series: Rapid Screw 90° Elbow with a fixed elbow configuration for standard directional routing.

• RPL-S Series: Rapid Screw Rotatable 90° Elbow, allowing the outlet direction to be repositioned for more flexible tube routing.

• RPL-G-S Series: Rapid Screw Rotatable 90° Elbow With O-ring, combining adjustable positioning with additional sealing at the threaded interface.

This range helps reduce unnecessary bends in pneumatic tubing and can make equipment layouts cleaner and easier to maintain.

Installation and Practical Pneumatic Applications

Installation is straightforward when the correct tubing size and thread specification are selected.

● Basic installation points:

• Confirm the fitting thread and tube dimensions before assembly.

• Install the threaded portion into a compatible pneumatic port and tighten appropriately.

• Insert the prepared pneumatic tube fully into the rapid screw connection.

• For rotatable models, adjust the elbow orientation to the required tubing direction.

• Check the connection for secure retention and leakage before operating the system.

RPL-SF, RPL-S and RPL-G-S stainless steel rapid screw fittings are suitable for industrial automation, packaging machinery, assembly equipment, robotics, pneumatic control systems, instrumentation, and compressed-air piping.

The fixed RPL-SF configuration works well for established layouts, while the rotatable RPL-S and RPL-G-S versions are useful when tube orientation needs to be adjusted during installation. With the additional O-ring option of RPL-G-S, the range provides flexible solutions for compact and reliable 90° pneumatic connections.
