In pneumatic piping, traditional threaded fittings require PTFE tape wrapping, thread alignment, and repeated tightening—time-consuming and labor-intensive, with a higher risk of leakage or damage, making maintenance more difficult.
Push-in fittings completely change this process—tubing can be connected and disconnected with a simple push and pull. This plug-and-play design delivers three key benefits: higher installation efficiency, easier operation, and more reliable sealing performance.
Fokca plastic push-in fittings are made of PBT, nickel-plated brass, and NBR seals, available in both metric and imperial sizes. They offer stable and reliable quality, suitable for most industrial applications with pressures below 1 MPa.
A push-in fitting is a key component in pneumatic systems used for quick connection between tubing and pneumatic devices. It features a push-to-connect design—simply insert the tube, and the internal gripping claws and seal automatically lock and seal it. For removal, press the release ring to easily pull out the tube without tools.
Compared with traditional threaded fittings, push-in fittings are lightweight, cost-effective, and easy to install, significantly reducing installation time, labor costs, and leakage risks caused by improper tightening. They are widely used in modern automation systems, including cylinders, solenoid valves, pneumatic tools, and robotic arms.
Fokca push-in fittings combine high-quality engineering plastics with precision metal components, offering a full range of types such as straight, elbow, tee, and bulkhead fittings for fast, reliable, and efficient connections.
· Push-to-connect, easy installation: One-touch connection—simply insert the tube to lock and seal automatically. Press the release ring for quick disassembly, saving time and effort.
· High-quality materials, reliable performance:
o Body: high-strength PBT engineering plastic (chemical-resistant, dimensionally stable)
o Metal parts: nickel-plated brass (anti-corrosion)
o Release ring: POM (wear-resistant, smooth operation)
o Seal: NBR rubber (oil-resistant, excellent sealing)
Dual sealing structure ensures long-term leak-free performance.
· Excellent performance, wide application:
Max pressure 1.0 MPa, working temperature -10°C to 60°C, vacuum up to -100 kPa. Suitable for compressed air and water applications.
· Full specifications, strong compatibility:
Tube OD: 4–16 mm (or 1/8"–1/2"). Thread types include metric (M5, M6) and BSPP (G), BSPT (R), NPT.
· Wide range of types:
Straight, elbow, tee, bulkhead, reducer, plug, etc., for flexible system layouts.
· Strict testing, dependable quality:
Pressure, leakage, and insertion cycle tests ensure stable grip, reliable sealing, and long service life.
· Customization available:
Custom colors, marking, and packaging options to meet branding and application needs.

· Tube cutting: Use a proper cutter to ensure a clean, burr-free, perpendicular cut
· Insertion & removal: Insert the tube fully, then pull gently to confirm locking; press the release ring to remove
· Bend radius: Avoid overly tight bends to prevent side load on the fitting
· Avoid rotation: Do not rotate the fitting after installation to prevent seal distortion
· For water use: Temperature ≤ 60°C, pressure ≤ 0.3 MPa, and avoid water hammer to protect sealing performance
