Stainless Steel Push-in Fittings – Ferrule-Type Compression Series

The Stainless Steel Push-in Fittings are designed for reliable pneumatic tubing connections where mechanical strength, corrosion resistance, and dimensional stability are essential. The ferrule-type compression structure provides a secure connection between the tube and fitting, while multiple configurations support different piping layouts. Available in FPL-S, FPU-S, FPV-S, FPB-S, FPC-S, and FPE-S Series, the range covers male elbows, straight fittings, 90° elbows, male tee branches, and tee branches. With 303, 304, 316, and 316L stainless steel options, these fittings can be selected according to the working environment and system requirements.

Ferrule Compression Designs for Flexible Pneumatic Layouts

This stainless steel push-in fitting range combines several connection configurations in one product family:

• FPL-S Series: Ferrule-type Compression Male Elbow for directional changes with a male threaded connection.

• FPU-S Series: Ferrule-type Compression Straight for direct tube-to-threaded connections.

• FPV-S Series: Ferrule-type Compression 90° Elbow for compact right-angle routing.

• FPB-S Series: Ferrule-type Compression Male Tee Branch for branching a pneumatic line while providing a male thread connection.

• FPC-S Series: Ferrule-type Compression Male Straight for straight-line pneumatic connections.

• FPE-S Series: Ferrule-type Compression Tee Branch for dividing airflow into two directions.

The ferrule compression construction is particularly suitable when a firm tube grip and stable sealing performance are required. The stainless steel body also provides strong resistance to corrosion and mechanical wear, making the fittings suitable for demanding industrial installations.

Materials, Threads and Manufacturing Quality

Different operating conditions require different material and connection options. These ferrule-type compression fittings are available in 303, 304, 316, and 316L stainless steel, allowing users to select a suitable grade based on corrosion exposure, cleanliness requirements, and application conditions.

● Key manufacturing features

• Automated production for most components to maintain consistent dimensions.

• Specialized inspection at critical manufacturing processes to control tolerances.

• Ultrasonic cleaning and drying before shipment.

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

• OEM and ODM customization with CAD drawings available according to customer requirements.

• ISO9001, CE, and FDA certificates.

These options make the series suitable for both standard pneumatic installations and customized equipment projects.

Installation and Pneumatic Applications

Installing the ferrule-type compression fittings requires the tubing to be properly cut and prepared before insertion. The tube should be clean, straight, and free from visible damage. Insert it into the fitting to the required depth and tighten the compression connection according to the applicable fitting specification. After installation, inspect the connection for proper tube retention and check the system for leakage before normal operation.

● Typical applications

• Factory automation and pneumatic control systems

• Packaging and assembly machinery

• Instrumentation and control equipment

• Food-processing and clean industrial equipment

• Corrosive or moisture-exposed pneumatic environments

• Pneumatic manifolds and compact tubing layouts

With straight, elbow, and tee configurations available, the series helps engineers build organized tubing networks while adapting connections to different installation spaces. For applications requiring special materials, dimensions, or connection configurations, OEM/ODM customization can further match the fitting to the pneumatic system.
