Tool-free installation drives faster line changes and reduces maintenance windows, increasing overall plant throughput. Feature → Business Impact → Application: The Pneufit C push-in design eliminates torquing and thread seals, delivering consistent, leak-free connections in automated circuits; this reduces commissioning time and minimizes production disruption on pneumatic lines across packaging and assembly lines. Feature → Real-world benefit → Application: The releasable stainless-steel grab-ring securely grips nylon or polyurethane tubing (85–95 durometer), enabling quick disconnections for testing or reconfiguration without compromise to seal integrity in high-velocity air paths. Feature → Silicone-free U-packing provides immediate quality sealing without silicone contamination, boosting part longevity and reducing sweep-up costs in clean manufacturing environments. Feature → Body made from plastic PBT with NBR seals (silicone-free) delivers corrosion resistance and extended service life, supporting dependable operation in hot and harsh factory settings. Feature → The compact 23 mm height, 45 mm length, and 30.5 mm width, plus a 0.02 kg weight, enable installation in tight spaces while maintaining robust performance under 0–10 bar and -20 to 60 °C. Feature → Tubing compatibility with PA2-0004100 and PA2-0004025C lengths (100 m and 25 m) expands sourcing options for varying line sizes and upgrade paths, reducing inventory complexity and improving procurement flexibility.

FAQs
The C02680438 uses a 4mm O/D tubing with a G3/8 port, designed for 0 to 10 bar operation and a -20 to 60 °C range. It accepts standard 4 mm O/D polyamide tubing and provides a tight, tool-free connection via the Pneufit C mechanism. Compatible tubing options include PA2-0004100 (100 m) and PA2-0004025C (25 m).
Installation is tool-free: insert the 4 mm O/D tube into the push-in port until it seats, then verify the stainless-steel grab-ring grips the tube. To disconnect, release the grab-ring, pull the tube free, and reinsert as needed. This minimizes downtime during line reconfigurations or maintenance.
Yes, the fitting features a releasable stainless-steel grab-ring and corrosion-resistant nickel-plated brass components, providing secure tube retention and durability in many vibration-prone applications. Operable across -20 to 60 °C and 0 to 10 bar, it suits standard automation environments with moving components.
Silicone-free U-packing eliminates silicone contamination risk, enabling cleaner fluid paths and reducing residues in sensitive systems. It delivers reliable immediate sealing on installation and minimizes maintenance-related downtime, improving process uptime in critical pneumatic lines.
PA tubing options include PA2-0004100, a 100 m reel, and PA2-0004025C, a 25 m reel, both in natural polyamide with 4 mm/2.5 mm coupling. These choices support different line lengths and deployment scenarios, helping optimize inventory and procurement for multiple production lines.
