Norgren C0KB00405 Pneufit C Push-in Fitting - 4mm
Part Number: C0KB00405
Quick Summary
Norgren Pneufit C Push-in fittings deliver fast, tool-free tube connections for compressed air systems. On busy production lines, time spent assembling and adjusting fittings slows changeovers and can introduce leaks. While certification data such as CE, SIL, or IP ratings isn’t listed in the provided data, Pneufit C components employ silicone-free U-packing and NBR seals to minimize contamination and improve reliability. The combination of nickel-plated brass for corrosion resistance and a stainless-steel grab-ring extends life in demanding environments, helping reduce replacement costs. This compact, shrouded banjo style connection is designed for 4 mm O/D tubing and M5 ports, offering easy integration in compact panels and automated assemblies, with clear business value in uptime and throughput.

Tool-free assembly and ready-to-use design reduce installation time and labor costs while improving line uptime in automated systems. The immediate seal with silicone-free U-packing minimizes contamination risk in clean pneumatic circuits, delivering more predictable performance. Benefit: faster changeovers and lower TCO on compressed air lines; Application: panel-mounted equipment and tight-space assemblies. Releasable stainless-steel grab-ring secures nylon or polyurethane tubing (85 or 95 durometer), enabling quick removal for maintenance or reconfiguration without sacrificing fit. Benefit: lower maintenance downtime and simplified field service; Application: rapid tube swaps in production environments. Nickel-plated brass components provide corrosion and contamination resistance, extending service life in harsh or humid environments and reducing retrofit or replacement costs. Application: outdoor machinery or wash-down areas. The shrouded banjo shape with 4 mm O/D tubing and M5 thread offers space-saving installation and flexible mounting options, improving machine layout and inventory efficiency. Benefit: compact footprint and faster stock rotation; Application: space-constrained control panels. The Pneufit C series uses a PBT body with NBR seals, rated for -20 to 60 °C and 0 to 10 bar, ensuring reliable performance across typical factory conditions. Benefit: predictable behavior and simplified spec alignment; Application: general-purpose compressed air circuits.

FAQs
C0KB00405 is designed for tool-free push-in assembly; no special tools are required for standard 4 mm O/D nylon or polyurethane tubing. The unit uses an M5 thread and 4 mm port, compatible with common PA2 tubing variants listed in the product details. For maintenance, simply depress the release tab to disconnect and re-seat the tube, ensuring a clean end for best sealing.)
Key specifications include operating temperature from -20 to 60 °C and operating pressure from 0 to 10 bar. These ranges support most factory environments and typical pneumatic circuits. The 4 mm O/D tube and M5 port enable compact, high-flow connections with minimal pressure drop, improving actuator response times and overall system efficiency.
Yes. The shrouded banjo design with a compact footprint (4 mm O/D, 25 mm length, 16 mm height, 23 mm width) fits tight panels and confined spaces. The tool-free push-in mechanism enables quick installation in crowded control cabinets, reducing assembly time and speeding up line changeovers without compromising seal reliability.
The provided data does not list CE, SIL, or IP certifications. For regulatory compliance details, consult the datasheet linked in the product downloads or contact the supplier. It is essential to verify certifications for your specific industry and application before deployment.
Expect lower maintenance downtime due to tool-free connection and field-replaceable tubes, plus longer service life from nickel-plated brass and corrosion resistance. Silicone-free U-packing reduces contamination risk, potentially lowering failure rates in sensitive pneumatic circuits and decreasing replacement costs over the equipment lifecycle.
