IMI Norgren C0TB00428 Pneufit C Push-in fitting - 4mm/ R1/4
Part Number: C0TB00428
Quick Summary
Pneufit C Push-in fitting offers fast, tool-free connections for compressed air lines in automated industrial systems. If you wrestle with lengthy assemblies, leaks from improper seals, or corrosion-prone components, this solution reduces downtime and maintenance costs. For critical applications, CE compliance, SIL readiness for safety-related lines, and IP-rated ruggedness are essential considerations when selecting fittings for harsh environments. With a nickel-plated brass body, silicone-free U-packing, and compatibility with 4 mm O/D tubing, C0TB00428 delivers reliable seals and extended service life. Its banjo shape and 4 mm port size simplify installation in tight panels and on multi-point manifolds. By combining tool-free assembly with robust materials, it helps reduce installation time, inventory complexity, and total cost of ownership.

Feature: Tool-free Push-in connection with a stainless-steel grab-ring provides fast, tool-free assembly and reliable tube retention, reducing commissioning time and the risk of mis-seated fittings. Business impact: Fewer tools required and fewer leakage points improve uptime across Pneufit C networks. Application: Best-suited for nylon or polyurethane tubes within the 85–95 durometer range and 4 mm O/D in compact panel manifolds. Feature: Nickel-plated brass body enhances corrosion resistance and contamination protection. Business impact: Extends service life in demanding manufacturing environments and lowers replacement costs. Application: Ideal for compressed air circuits in automotive, packaging, and general automation environments. Feature: Silicone-free U-packing enables immediate quality sealing without introducing silicone residues into the air stream. Business impact: Maintains air purity for downstream actuators and sensors, reducing maintenance and contamination risk. Application: Critical in clean-air circuits and processes with sensitive components or ISO-clean requirements. Feature: Releasable stainless-steel grab-ring ensures secure tube grip and easy disassembly. Business impact: Facilitates maintenance and cross-compatibility with existing tubing stocks. Application: Works with nylon or polyurethane tubes and supports quick tube replacement in tight spaces. Feature: Banjo shape with 4 mm port size and R1/4 thread offers compact mounting. Business impact: Simplifies installation in panel-mounted manifolds and tight enclosures. Application: Suitable for multi-point pneumatic networks using 4 mm O/D tubing. Feature: PA2-0004100 and PA2-0004025C tubing options extend system compatibility. Business impact: Reduces spare-part variety and streamlines procurement. Application: Aligns with standard polyamide tubing to support consistent performance across lines.

FAQs
To install the C0TB00428, cut the 4 mm O/D tubing square, insert it into the push-in port until the stainless-steel grab-ring engages, and verify a leak-free seal. The tool-free design eliminates the need for wrenches or clamps, reducing setup time on crowded panels. Ensure the tube ends are clean and free of burrs for best performance.
Yes. The Pneufit C C0TB00428 is compatible with PA2-0004100 (100 m, 4 mm/2.5 mm) and PA2-0004025C (25 m, 4 mm/2.5 mm) polyamide tubes. These PA tubing options provide consistent O/D size and material properties, ensuring reliable seals with the silicone-free U-packing and nickel-plated brass body.
The operating temperature range is -20 to 60 °C (-4 to 140 °F), and the operating pressure range is 0 to 10 bar (0 to 145 psi). These limits support typical factory pneumatic applications and ensure stable performance across standard automation environments.
The leak-tight performance comes from a silicone-free U-packing material combined with a releasable stainless-steel grab-ring and corrosion-resistant nickel-plated brass components. This combination minimizes the risk of silicone contamination in the air stream while delivering reliable, repeatable seals across cycles.
Expected ROI stems from reduced installation time due to tool-free push-in assembly, lower maintenance from durable nickel-plated brass and corrosion resistance, and fewer leaks thanks to silicone-free sealing. These factors collectively shorten commissioning, improve uptime, and reduce replacement and inventory costs in multi-point pneumatic networks.
