Tool-free push-in operation reduces installation time and labor costs while delivering secure, repeatable connections in high-demand environments. The stainless-steel grab-ring grips nylon or polyurethane tube (85 or 95 durometer) for fast, tool-less disconnections and reliable reuse in changeovers, maintenance, or reconfigurations—ideal for responsive packaging lines and quick-turn test rigs. Nickel-plated brass components provide corrosion and contamination resistance, extending component life in humid or dirty manufacturing environments and reducing total cost of ownership. The silicone-free U-packing with NBR seals eliminates silicone contamination concerns in sensitive pneumatic circuits, improving product quality and system cleanliness. The Banjo-shaped body with 12 mm O/D tube and G1/2 port supports compact manifold designs and flexible routing in space-constrained equipment, boosting cabinet density and installation simplicity. Compatibility with polyamide tubing PA2-0012025C and PA2-0012100 enables straightforward stock management and rapid scaling across multiple lines, while the Pneufit C family adheres to established piping standards for consistent interchangeability. Operating in a broad temperature range (-20 to 60 °C) and a pressure range (0 to 10 bar) makes this fitting suitable for varied industrial environments, from robotics cells to pneumatic actuators, reinforcing system uptime and process efficiency.

FAQs
To install, simply insert the 12 mm O/D tube into the push-in port until it seats with a tactile click. The stainless grab-ring secures the tubing without tools, enabling quick changeovers. For removal, depress the release mechanism to disengage the tube and pull it free. This process minimizes downtime on assembly lines and reduces installation errors common with crimp or compression fittings.
The C0H7K1248 is rated for an operating temperature from -20 to 60 °C and an operating pressure range of 0 to 10 bar. These specifications make it suitable for typical factory pneumatic circuits, robotics, and automation panels where ambient conditions and compressed air supply vary. Always verify system pressure and temperature uniformity to avoid binding the seal or causing flow restrictions.
Yes. The Banjo-shaped body with a G1/2 port is designed for compact manifold integration and flexible routing in multi-port pneumatic assemblies. This configuration supports dense panel layouts, easy access for service, and straightforward integration with 12 mm O/D tubing, reducing overall pipework length and improving airflow efficiency on automated lines.
Pneufit C components typically feature CE conformity and applicable IP ratings, with SIL-ready options for safety-related control circuits. Certification status varies by variant, so always check the datasheet for the exact model. Compliance ensures safer operation in critical automation environments and supports qualification for machinery that requires regulatory adherence in production lines.
Tool-free installation and tool-free disconnection accelerate setup and reconfiguration, reducing labor costs and downtime. The silicone-free U-packing minimizes particulate contamination, helping maintain actuator performance. Nickel-plated brass resist corrosion, extending service life in challenging environments. Together with compatibility to PA tubing, these factors streamline spare-part management, lower total cost of ownership, and improve overall equipment uptime.
