Tool-free push-in connection reduces assembly steps and field downtime, enabling rapid line changes and less need for dedicated tooling; this translates to faster deployments on packaging lines and robotic cells. The releasable stainless-steel grab-ring securely grips nylon or polyurethane tubes (85 or 95 durometer), minimizing risk of tube displacement and leaks in dynamic automated systems. Nickel-plated brass components deliver corrosion and contamination resistance, extending service life in oily or humid factory environments and reducing spare parts consumption. Silicone-free U-packing provides immediate, reliable sealing without silicone contamination, improving product cleanliness in food, pharmaceutical, and clean-room compatible lines. The body uses a lightweight PBT polymer with NBR seals, balancing chemical compatibility and cost. Compact dimensions (63 mm length, 32.7 mm width, 20.8 mm height) and a 0.07 kg weight simplify manifold layouts and integration with standard 4 mm tubing and R1/4 thread interfaces. Overall, Pneufit C improves installation times, reliability, and lifecycle costs in industrial automation and machine-building projects.

FAQs
This adaptor is designed for 4 mm O/D tubing and accepts standard nylon or polyurethane tubes, typically 85–95 durometer. It uses a releasable stainless-steel grab-ring to secure the tube, minimizing slip and leaks in dynamic pneumatic circuits.
The tool-free push-in mechanism removes the need for clamps, ferrules, or tools, reducing assembly steps and downtime. In tight manifolds, this simplifies field changes, lowers installation error rates, and accelerates machine commissioning while maintaining reliable seals.
The body is plastic PBT with nickel-plated brass components for corrosion resistance. Seals use NBR that is silicone-free, reducing silicone contamination risk in sensitive processes. This combination supports long service life and predictable performance across typical industrial environments.
Yes. The operating temperature range is -20 to 60 °C (-4 to 140 °F), which aligns with many automation environments. Ensure compressed air quality is within spec and avoid exposure to extreme contaminants that could affect seals or body materials.
Plan for periodic inspection of the tube fit and seals, particularly if tubing materials or durometer ratings change. Verify compatibility with 4 mm O/D tubes and R1/4 threads in your manifold, and consult the datasheet for installation guidelines and replacement parts to sustain peak performance.
