Norgren C0KB00418 Pneufit C Push-in Fitting - G1/8
Part Number: C0KB00418
Quick Summary
Pneufit C Push-in Fitting is a fast, tool-free connection for compressed air lines in automated equipment. Engineers often struggle with long assembly times and leak-prone joints when wiring or plumbing pneumatic systems in compact panels. The design delivers silicone-free U-packing for immediate sealing, a releasable stainless-steel grab-ring for reliable tube grip, and nickel-plated brass for corrosion resistance and durable life. For formal certifications, confirm CE marking, IP protection, and SIL conformity with your facility requirements, as these are not explicitly listed in the data but are common in industrial deployments. Overall, this fitting reduces downtime, improves reliability, and lowers lifecycle costs in automation, robotics, and packaging lines that use 4 mm tubing with G1/8 ports.

The tool-free push-in connection reduces installation time and minimizes human error, delivering faster commissioning and lower labor costs in busy production lines while maintaining reliable seals in dynamic pneumatic networks. The releasable stainless-steel grab-ring provides secure grip on nylon or polyurethane tubes (85 or 95 durometer), enabling quick tube changes during line reconfiguration without tools, which translates to reduced downtime and adaptable manufacturing cells. Silicone-free U-packing ensures immediate, contamination-free sealing, improving leak resistance and extending component life in clean-room or food-grade environments where silicone contamination must be avoided. The nickel-plated brass body offers corrosion resistance and long service life in challenging factory environments, supporting predictable performance and reduced maintenance. Operating with compressed air (medium) at -20 to 60 C and 0 to 10 bar, the Pneufit C fits 4 mm O/D tubing and G1/8 ports, delivering robust compatibility for standard automation hardware. The PBT body and NBR seals (silicone-free) balance strength with chemical compatibility, helping to prevent swelling or degradation under normal plant conditions. Compatibility with polyamide tubes PA2-0004100 (100 m, 4 mm) and PA2-0004025C (25 m, 4 mm) enhances stock optimization and installation flexibility for project-wide pneumatic plumbing.

FAQs
To install the C0KB00418, insert the 4 mm O/D tubing into the push-in fitting until it seats fully. The tool-free design eliminates the need for wrenches or clamps, reducing assembly time. Use the stainless-steel grab-ring to release or replace the tube as needed, ensuring the Nylon or PU tube remains securely gripped. Confirm the G1/8 thread and 4 mm O/D tube match your manifold and panel connections, and verify there are no barb or misalignment issues before pressurizing.
This Pneufit C fitting operates from -20 to 60 °C (-4 to 140 °F) and supports 0 to 10 bar (0 to 145 psi) of compressed air. It is designed for medium of compressed air with a 4 mm O/D tube, G1/8 port, and banjo shape. When selecting for high-heat or high-pressure environments beyond these ranges, consider alternative fittings or additional cooling and pressure management to maintain seal integrity.
Yes. The banjo geometry and 4 mm O/D tube compatibility suit compact, panel-mounted pneumatic networks common in robotics and packaging lines. The tool-free Push-in mechanism accelerates field assembly and reconfiguration, while the silicone-free U-packing reduces contamination risk. The combination of NBR seals and nickel-plated brass body delivers reliable sealing and corrosion resistance, making it well-suited for rugged manufacturing environments where space is at a premium.
The provided data does not specify explicit CE, IP, or SIL certifications for this part. In practice, verify CE marking, IP protection level, and SIL conformity with your specific project and regional regulations. The device features silicone-free seals and corrosion-resistant materials, which support compliance efforts, but final certification status should be confirmed with the supplier and your internal quality team.
The Pneufit C design emphasizes low maintenance and long life. Silicone-free U-packing reduces contamination risk and supports immediate, reliable seals, while a corrosion-resistant nickel-plated brass body extends service life in challenging environments. The tool-free installation minimizes downtime during commissioning and reconfiguration, contributing to faster project ROI and lower total cost of ownership in continuous-fabrication or high-changeover environments.
