Norgren M02670406 Pneufit M Push-in Fitting - 4mm M6 Tee
Part Number: M02670406
Quick Summary
Pneufit M push-in fittings deliver fast, tool-free connections for compressed air lines in compact automation assemblies. Engineers often face tight spaces and time-consuming installations that increase downtime; this adaptor helps streamline panel layouts and cut cycle times. The Pneufit M family is designed for robust performance in demanding environments, featuring releasable stainless-steel grab rings, nickel-plated brass components, and pre-applied thread sealant to ensure reliable seals. With a compact footprint and space-saving geometry, these fittings integrate smoothly into multi-port manifolds and close-quarters circuits. Compatibility with PA2-0004100 and PA2-0004025C tubing broadens system design options, while the approach supports standard maintenance practices and supply-chain efficiency for OEMs and integrators.

Feature → Business Impact → Application: Tool-free push-in connection with releasable grab ring reduces installation time and enables quick disconnection for maintenance. This improves line availability and lowers labor costs in assembly cells and service loops, particularly in tight panel spaces where 4mm O/D tubing is common. Feature → Benefits: The nickel-plated brass body delivers corrosion and contamination resistance in demanding environments, extending component life and reducing replacement intervals in factory floors and automated lines. Application: Use in compressed-air circuits requiring high reliability and low leak paths, such as pick-and-place machines and pneumatic clamps. Feature → Benefits: Pre-applied thread sealant on taper threads guarantees rapid, repeatable seals, minimizing retry iterations during assembly and commissioning in new builds and retrofits. Application: Ideal for zero-maintenance installations in robotic cells and process automation. Feature → Benefits: Internal and external hex engagement facilitates tool-efficient installation with standard wrenches, supporting field service and module expansions. Application: Field upgrades, panel-mounted manifolds, and compact distribution blocks. Feature → Benefits: Compact dimensions (29 mm length, 20.7 mm width, 10.4 mm height) and light weight (0.06 kg) maximize space, enabling dense manifold designs and easier routing in small cabinets. Application: Small-form-factor pneumatic systems and equipment upgrades. Feature → Benefits: Material mix (PBT body, nitrile seals) and silicone-free U-packing deliver reliable sealing while resisting chemical exposure and contamination. Application: Food processing, electronics assembly, and automotive automation where clean, leak-proof connections are essential. Feature → Benefits: Compatibility with PA2-0004100 and PA2-0004025C tubing broadens supply options and supports standard piping practices in plastics and metal automation environments. Application: System redesigns, budget-conscious projects, and retrofit programs seeking flexible tubing choices.

FAQs
Installation is tool-free and uses a releasable grab ring to grip the 4 mm O/D tube. Align the tube, push in firmly until seated, and release the ring to secure. The pre-applied thread sealant on taper threads aids rapid sealing, while the external hex allows easy hand or standard wrench engagement during assembly or removal. This streamlines commissioning and reduces the chance of leaks during field service.
The fitting is designed for 4 mm O/D tubing. It is compatible with PA2-0004100 Polyamide tube (Natural, 100 m, 4 mm/2.5 mm) and PA2-0004025C (Natural, 25 m, 4 mm/2.5 mm). These options provide flexibility for long runs or short segments within compact pneumatic networks while maintaining reliable, leak-free connections.
Yes. The M02670406 is part of the Pneufit M line, engineered for ultra-compact space conditions with a 29 mm length, 20.7 mm width, and 10.4 mm height. Its slim profile, combined with a small footprint and precise push-in action, makes it well suited for dense manifolds, close-placed valves, and robotics cells where space is at a premium.
The silicone-free U-packing reduces silicone residue concerns in sensitive pneumatic circuits, while nitrile seals provide dependable sealing against standard compressed air contaminants. For best results, operate within the specified temperature (-20 to 60 °C) and pressure (0–10 bar). Periodic inspection of seals and grub ring condition is recommended in high-cycle applications to preserve seal integrity.
