Norgren M02680303 Pneufit M Tee Fitting - 3mm M3
Part Number: M02680303
Quick Summary
Pneufit M push-in fittings deliver fast, tool-free connections for compressed air in tight spaces. On dense automation lines, installation ease can be the difference between a smooth run and recurring bottlenecks. Industry engineers evaluate CE compliance, IP protection considerations, and SIL reliability when selecting panels and safety circuits. Model M02680303 pairs a compact tee body with pre-applied thread sealant and a releasable grab ring to simplify routing and service. Its nickel-plated brass components resist corrosion while silicone-free U-packing provides immediate sealing, extending life in demanding pneumatic systems. This combination supports lean manufacturing by delivering predictable, leak-free performance with fast maintenance in small-bore tube installations.

Push-in, tool-free connections enable rapid assembly, reducing setup time and training requirements while lowering labor costs in production lines. The immediate sealing provided by silicone-free U-packing minimizes leak paths, contributing to safer, more efficient compressed air systems. Compact Pneufit M geometry fits into limited spaces, improving panel density and enabling cleaner routing for small-diameter tubing such as 3 mm O/D lines used in automated equipment. A releasable stainless-steel grab ring grips nylon or polyurethane tubes (85 to 95 durometer), simplifying removal and service without tube damage. Pre-applied thread sealant on taper threads accelerates assembly and reduces potential leak points during installation. Nickel-plated brass components offer corrosion resistance and long life in challenging environments, while internal and external hex surfaces on straight fittings ease installation with common tools. The body is formed from PBT with nitrile seals, balancing chemical compatibility and durability in compressed-air circuits. Mounting holes on all union fittings provide flexible mounting options for panels and manifolds, helping to minimize vibration and misalignment in dynamic systems. The product range (M0168, M0268) confirms compatibility with a family of Pneufit M fittings, and the included PU tubing (3 mm ID, 2 mm) supports quick integration into existing lines. Overall, M02680303 delivers a reliable, compact, and service-friendly solution for tight-quota installations in factory automation, robotics cells, and small-scale pneumatics.

FAQs
The M02680303 is designed for 3 mm O/D tubing and M3 thread interfaces. To install, push the tubing into the push-in port until the releasable grab ring engages, then verify seating by gently tugging. Pre-applied taper-thread sealant aids rapid, leak-free assembly. This approach minimizes installation error and supports quick line changes in automated lines.
This Pneufit M Tee is specified for use with compressed air at temperatures from -20 to 60 °C and pressures from 0 to 10 bar (0 to 145 psi). These ranges align with common factory floor environments, enabling reliable performance in standard pneumatic circuits without special cooling or heating provisions.
Yes. The ultra-compact three-port tee design is ideal for space-constrained panels and robotic cell installations. Its compact footprint, combined with a 3 mm O/D tubing option and M3 thread, allows clean routing in tight enclosures while maintaining robust, tool-free connections and quick maintenance access.
Engineers typically consider CE conformity and general safety/reliability standards when integrating pneumatic fittings like the Pneufit M. In addition, design practices often account for IP protection considerations and SIL reliability in safety-critical circuits, ensuring compliant and dependable operation in automation environments.
The tool-free push-in mechanism reduces maintenance time and the risk of cross-thread damage during service. Silicone-free U-packing provides immediate sealing, reducing leak-related energy losses. Releasable grab rings simplify disassembly for tube replacement, cutting downtime and extending the service life of pneumatic circuits in continuous manufacturing environments.
