Norgren C0B700428 Pneufit C Push-in Adaptor - 4mm G1/4
Part Number: C0B700428
Quick Summary
Pneufit C push-in fittings provide tool-free assembly for compressed air lines in automation and factory pneumatics. This approach eliminates fiddly tools, reduces setup time, and lowers contamination risk during manifold mounting. CE compliance and robust IP-rated variants are common expectations for pneumatic fittings, while SIL-rated configurations are application-specific. For OEMs and integrators, this adaptor's compact form factor and corrosion-resistant materials translate to shorter install times and longer service life, enabling you to scale panel builds with confidence. The 4 mm tubing and G1/4 port compatibility support standard pneumatic networks, while silicone-free NBR seals improve reliability in demanding environments.

Tool-free, ready-to-use design shortens installation time and reduces field errors, delivering faster commissioning and less downtime on complex pneumatic manifolds. This directly translates to improved line throughput and lower labor costs. The robust push-in connection is ideal for 4 mm O/D tubing, enabling rapid reconfigurations in high-mix manufacturing environments and packaging lines. In practice, engineers gain repeatable seals and straightforward maintenance workflows, which minimizes leak points and accelerates troubleshooting in automated systems. The adaptor’s stainless-steel grab-ring (releasable) secures 85–95 durometer nylon or polyurethane tubes, allowing quick disconnections for service without tools, reducing maintenance windows and inventory headaches. This compatibility supports common tube materials used in OEM assemblies and field retrofits. Nickel-plated brass bodies resist corrosion and contamination, extending product life in harsh factory conditions and contributing to reduced replacement costs. Silicone-free U-packing provides immediate, reliable sealing, supporting clean-air applications and helping meet stringent contamination standards in pneumatic circuits. The PBT body, combined with 4 mm O/D tubing and G1/4 threads, yields a compact manifold profile that fits tight panels and multi-branch configurations, lowering panel footprint and simplifying installation across automation cells. With a weight of 0.06 kg and precise dimensions (Height 31 mm, Length 61 mm, Width 33 mm), the Pneufit C adaptor is easy to inventory and spec across multiple machines, helping maintain consistent part families and minimizing configurational variance in production lines.

FAQs
Yes. The adaptor is designed for 4 mm O/D tubing and features G1/4 threads, enabling straightforward integration into standard pneumatic networks. It supports nylon or polyurethane tubes (85–95 durometer) and requires no special tools for mounting or disassembly, which speeds up installation on OEM panels and retrofit projects.
The Pneufit C adaptor uses a plastic PBT body with NBR seals that are silicone-free, and a nickel-plated brass interface for corrosion resistance. It is rated for an operating temperature of -20 to 60 C and weighs 0.06 kg, making it suitable for typical factory environments and a broad range of pneumatic circuits.
This adaptor excels in automation panels, multi-branch manifolds, robotics cells, packaging lines, and OEM pneumatic circuits where quick installation, compact footprint, and reliable sealing are critical. Its small form factor (31 mm height, 61 mm length, 33 mm width) helps maximize panel space while maintaining strong flow and seal performance.
Certification status for CE or SIL and IP ratings depends on the specific variant and application. The Pneufit C family typically aligns with common industry requirements, but you should verify the datasheet and part-specific documentation for definitive certification statuses and regulatory compliance before use in regulated environments.
Tool-free installation reduces commissioning time and first-time setup costs, while silicone-free seals and corrosion-resistant materials lower leakage and replacement frequency. The ability to disassemble quickly without tools simplifies preventive maintenance, minimizes downtime, and lowers total cost of ownership across multiple machines and lines.
