IMI Norgren C0B711238 Pneufit C Fitting - Silicone-free
Part Number: C0B711238
Quick Summary
Pneufit C Fitting enables tool-free, push-in assembly for compressed air lines in automation projects. Engineers confront leak paths, misalignment, and slow installations when working in tight spaces or on legacy piping. While many pneumatic components rely on standard seals and robust housings, this model emphasizes silicone-free U-packing and corrosion-resistant materials to minimize contamination and extend service life. The stainless-steel grab-ring provides a secure grip even with nylon or polyurethane tubing, and the 12 mm O/D tube compatibility ensures straightforward integration into existing circuits. For project teams, this means faster assembly, reduced downtime, and predictable performance across a range of industrial applications, from packaging lines to automated test rigs. In regulated environments, CE, IP, and SIL considerations are common benchmarks to verify; consult the datasheet for applicable certifications.

Tool-free push-in operation is at the core of Pneufit C fittings, reducing installation time and training requirements while enabling rapid field reconfigurations in automation lines. This translates to higher line uptime and lower labor costs, especially in high-mix manufacturing environments where frequent changes are required. The releasable stainless-steel grab-ring securely grips nylon or polyurethane tubes (85 or 95 durometer), enabling fast disconnections during maintenance without compromising leak integrity or system pressure. Silicone-free U-packing provides immediate, reliable sealing while avoiding silicone contamination in sensitive pneumatic circuits, which is particularly important for clean manufacturing processes and downstream assembly. The body utilizes a durable PBT material with NBR seals, delivering corrosion resistance and extended life in harsh factory environments, reducing replacement cycles and total cost of ownership. Compact dimensions (12 mm O/D tube, G3/8 thread) and a cross-shaped configuration yield a small footprint, simplifying installation in crowded panels and enabling straightforward retrofits into existing Pneufit C networks. Overall compatibility with standard 12 mm tubing and G3/8 ports supports scalable system design, ensuring easy integration with existing compressed air circuits and minimizing rework during upgrades. This combination of features delivers measurable gains in efficiency, contamination control, and system reliability across automotive, packaging, and general industrial automation applications.

FAQs
The C0B711238 supports a 12 mm outer diameter tube with a G3/8 thread. It uses a cross-shaped body and a stainless-steel grab-ring to secure nylon or polyurethane tubes. For best results, ensure your tubing is 85–95 durometer and that the silicone-free NBR seals are compatible with your media to maintain leak-free performance.
The Pneufit C delivers tool-free push-in assembly, minimizing assembly time and training needs. The silicone-free U-packing provides immediate, reliable sealing without silicone contamination, which is crucial in clean manufacturing environments and sensitive pneumatic circuits. Combined with a stainless-steel grab-ring, it enables quick maintenance and repeatable disconnections without compromising integrity.
This fitting is designed for compressed air with an operating temperature range of -20 to 60 °C (-4 to 140 °F). It features a PBT body and NBR silicone-free seals, balancing durability with chemical resistance. Use within these parameters to maintain optimal performance and avoid seal degradation or material compatibility issues with aggressive media.
Yes, for typical automation environments the Pneufit C offers a robust combination of materials and hardware, including a stainless-steel grab-ring and corrosion-resistant nickel-plated brass components. The silicone-free U-packing helps maintain seal integrity without silicone contamination. For extremely high-vibration applications, validate mounting orientation and consider periodic inspection of the seal interface as part of your preventive maintenance plan.
