SPD & SPD-G Series Stainless Steel Push-in Fittings

Three-Way Pneumatic Connections in a Compact Structure

The SPD and SPD-G Series Stainless Steel Push-in Fittings provide a practical way to create three-way pneumatic connections without adding unnecessary adapters or connection points. Their male tee branch configuration combines a threaded male port with two tube connection paths, allowing a pneumatic component and an additional air line to be integrated into one fitting.

The SPD Series Male Tee Branch is intended for standard three-way connection requirements, while the SPD-G Series Male Tee Branch With O-ring adds an O-ring sealing element to the threaded connection. This additional sealing structure helps improve connection stability and provides a more reliable interface where leakage control is important.

The compact tee geometry also helps engineers maintain organized tubing layouts around valves, cylinders, manifolds, and other pneumatic components.

Stainless Steel Construction for Long-Term Reliability

Manufactured from 303, 304, 316, and 316L stainless steel, these pneumatic fittings offer strong resistance to corrosion, moisture, and general industrial wear. Different material grades allow users to select a suitable option according to the operating environment and equipment requirements.

Production is supported by automated manufacturing equipment, while critical processes are checked by specialized inspectors to ensure dimensional consistency and required tolerances.

● Key characteristics include:

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

• Male Tee Branch and Male Tee Branch With O-ring configurations.

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

• OEM and ODM customization supported.

• CAD drawings can be provided according to customer requirements.

• Ultrasonic inspection, cleaning, and drying before shipment.

• ISO9001, CE, and FDA certifications.

Fast Push-in Assembly and Secure Thread Installation

The push-in connection allows pneumatic tubing to be installed quickly by inserting the prepared tube directly into the fitting. This simplifies assembly and can reduce installation time when multiple connections are required.

The male threaded portion is installed into a compatible female port on the pneumatic component. For the SPD-G version, the integrated O-ring provides additional sealing at the threaded interface. During installation, the thread should be tightened to the appropriate level without excessive force, while the tubing should be cut cleanly and inserted fully into the push-in port.

Applications Across Industrial Pneumatic Systems

SPD and SPD-G Series stainless steel push-in fittings are suitable for industrial automation, pneumatic control equipment, packaging machinery, robotics, assembly systems, instrumentation, and compressed-air circuits.

The male tee structure is especially useful when a component connection and air-line branching need to be achieved at the same location. The SPD-G version offers an additional sealing solution for applications where connection stability is a higher priority.

With corrosion-resistant stainless steel materials, flexible thread specifications, and two configuration options, the SPD and SPD-G Series provide a dependable solution for compact three-way pneumatic connections.
