Norgren M022A0406 Pneufit M Fitting - Internal Hex
Part Number: M022A0406
Quick Summary
Pneufit M push-in fittings deliver tool-free, fast connections for compact pneumatic lines on automation equipment. In crowded panels, traditional screw fittings slow assembly and create leak risks. It aligns with CE requirements and supports IP-rated environments, with SIL-ready options for safety-critical architectures. For OEMs and maintenance teams, this design translates to shorter changeovers and fewer parts to stock, while maintaining reliability. The solution pairs seamlessly with PA2 tubing and standard 4 mm O/D tubes, enabling flexible, cost-effective system design, and it helps you meet cleanliness and regulatory standards while reducing total cost of ownership.

FAQs
The M022A0406 is a straight Pneufit M adaptor with a 4 mm O/D tube interface and an M6 taper thread. It uses pre-applied thread sealant for rapid sealing, a nickel-plated brass body for durability, and a nitrile seal. It is designed to work with PA2-0004100 and PA2-0004025C tubing options, ensuring reliable, tool-free connections in compact pneumatic circuits.
Pneufit M features an ultra-compact form factor, internal and external hexes for easy wrench access, and a tool-free push-in actuation. These elements reduce installation time, allow closer packing of components, and minimize leakage risk. In high-density panels, users gain faster maintenance cycles and lower overall assembly costs without compromising seal integrity.
The Pneufit M design supports CE regulatory expectations and is compatible with IP-rated environments. While certifications may vary by variant and region, the materials (PBT body, nitrile seals) and robust construction are chosen to meet common industrial safety and environmental considerations. For safety-critical systems, SIL-focused architectures can be accommodated through compliant system design and compatible components.
Nickel-plated brass components deliver superior corrosion resistance and extended service life, reducing maintenance frequency in challenging environments. The silicone-free U-packing minimizes contamination risk, and the releasable stainless-steel grab ring ensures secure, reusable tube retention. Together, these features translate to fewer leaks, longer intervals between service, and lower total cost of ownership.
ROI benefits stem from tool-free, rapid installation, reduced parts and labor costs, and fewer leak-related downtime events. The compact form factor enables denser panel layouts, while durable materials reduce replacement parts and field servicing. For high-volume lines using 4 mm tubing and M6 connections, Pneufit M delivers measurable gains in uptime and production throughput.
