Norgren C0B511248 Pneufit C - 12 mm silicone-free seals
Part Number: C0B511248
Quick Summary
Pneufit C Push-in fitting enables tool-free, fast connections for compressed air in automated equipment and distribution manifolds. End users frequently grapple with slow assembly, leaks, and misalignment when traditional fittings are installed in tight spaces. The dataset does not specify certifications; typical buyers verify CE marking, SIL ratings, and IP protection in the datasheet. The combination of silicone-free NBR seals, a releasable stainless-steel grab-ring, and a compact PBT body delivers reliable performance, reduces downtime, and supports scalable automation in modern industrial environments.

Feature: Tool-free push-in design enables fast, tool-free installation with secure, positive sealing. Benefit: Reduces labor time and downtime, improving line throughput in automated cells and distribution manifolds. Application: Ideal for high-mix manufacturing lines where quick reconfiguration is required and space is at a premium. Feature: Releasable stainless-steel grab-ring grips nylon or polyurethane tubing (85 or 95 durometer) for reliable retention and easy removal. Benefit: Minimizes tube slip under vibration and simplifies maintenance in rugged environments. Application: Suitable for 12 mm O/D tubing in compact pneumatic circuits. Feature: Nickel-plated brass bodies provide corrosion resistance and long life in harsh environments. Benefit: Extends service intervals and lowers replacement costs in harsh factory floors. Application: Aggressive cleaning regimes or outdoor installations. Feature: Immediate quality sealing using silicone-free U-packing eliminates silicone contamination in compressed air lines. Benefit: Improves air purity and protects downstream components, reducing defect rates. Application: Food-grade or clean-room related pneumatic systems where contamination control is critical. Feature: Materials and dimensions—body in PBT, seals in NBR (silicone-free), 27.7 mm height, 70 mm length, 51.2 mm width, 0.15 kg weight. Benefit: Compact form factor supports tight installations and easy handling during assembly. Application: Space-constrained panel manifolds and modular automation layouts. Feature: Port size G1/2 with 12 mm O/D tube and G1/2 thread; Shape: Manifold. Benefit: Streamlines connection strategies for multi-port manifolds and simplifies stocking of standard components.

FAQs
Installation is tool-free: cut the tubing square, insert into the fitting until the stainless-steel grab-ring engages, and orient the elbow as needed. The 12 mm O/D tube fits the G1/2 port and the double swivel elbow helps align the tube in tight spaces, reducing misalignment and leaks.
The fitting is designed for compressed air and operates from -20 to 60 °C (-4 to 140 °F). It supports standard pneumatic applications with 12 mm O/D tubing and G1/2 threads, making it suitable for most general automation panels and manifolds.
Yes. The port size is G1/2 and the tube diameter is 12 mm, with a 12 mm outer diameter on the tubing. The design includes a double swivel elbow to accommodate orientation in restricted spaces, facilitating quick assembly in multi-port manifolds.
The unit uses NBR seals that are silicone-free, reducing the risk of silicone contamination in the air path. This improves air cleanliness and downstream component life. Ensure system compatibility with NBR seals for your application and verify any oil compatibility requirements in your process.
Expect reduced downtime from tool-free, rapid assembly and fewer leaks thanks to silicone-free sealing. The durable PBT body and nickel-plated brass components resist corrosion, lowering maintenance and replacement costs while enabling faster line changes and more flexible automation layouts.
