Norgren S01670428 Pneufit S - Stainless steel push-in tee adaptor 316L
Part Number: S01670428
Quick Summary
Pneufit S stainless steel push-in fitting provides fast, secure tubing connections for compressed air systems in harsh environments. Engineers often struggle with aggressive media, tight spaces, and downtime caused by difficult tube insertion and removal. CE‑marking concepts, robust IP‑rated considerations, and SIL‑capable safety integration are commonly required for compliant, safe installations. Resistant to aggressive environments and suitable for demanding manufacturing settings, including food and beverage lines, this solution reduces leak paths and downtime. Compatibility with standard 4 mm OD tubing and R1/4 threads simplifies procurement, while the hex socket option in straight adapters aids rapid field installation.

The stainless steel AISI 316L body provides outstanding corrosion resistance, extending service life in aggressive environments and reducing total cost of ownership for pneumatic systems. This translates into measurable business benefits such as lower replacement costs and reduced maintenance intervals in harsh plants, including those handling food and beverage processes. The compact, lightweight design enables tight routing and easier installation in space-constrained panels, delivering faster assembly times and improved line uptime for critical production lines. With a 4 mm outer diameter tube and R1/4 thread, the fitment integrates smoothly with common pneumatic components, limiting the need for multiple adapters and simplifying parts management. Positive tube anchorage ensures reliable sealing even under vibration, enhancing system reliability and reducing leak-related losses across continuous operation. The Pneufit S concept also features hex socket compatibility on straight adapters, enabling tool-assisted assembly that minimizes torque damage and ensures consistent tightening in field conditions. This combination supports safer, more efficient maintenance cycles and predictable performance in both general manufacturing and specialized environments. For added versatility, this family accommodates PA2 polyamide tubing options, enabling quick, low-cost tubing upgrades without sacrificing reliability. In short, the design delivers rapid assembly, robust endurance, and simplified maintenance for pneumatic circuits in demanding applications.

FAQs
To install, insert the 4 mm OD polyamide tube into the push-in port until it seats with a positive retention. The design provides easy insertion and removal for rapid assembly of pneumatic circuits. For straight adapters, use the hex socket with a hex key to ensure proper torque and a reliable seal. Always verify that the tube is fully seated and that the connection is free of burrs or damage before pressurizing the line.
This Pneufit S adaptor is rated from -15 to 190 °C (-5 to 374 °F) and supports operating pressures from -0.9 to 20 bar (-14.5 to 290 psi). These ranges enable use in a wide variety of industrial and processing environments, including demanding manufacturing lines that require robust performance under thermal cycling and vibration.
Yes, the Pneufit S series is designed for resistance to aggressive environments and is suitable for food and beverage applications. The 316L stainless steel body provides corrosion resistance and cleanliness advantages, supporting hygienic and compliant pneumatic installations in processing and packaging lines.
The fitting accepts 4 mm outer diameter tubing and uses an R1/4 thread. It is compatible with standard PA2 polyamide tubes such as PA2-0004100 (100 m, 4 mm/2.5 mm) and PA2-0004025C (25 m, 4 mm/2.5 mm), enabling straightforward integration into existing pneumatic circuits without extensive reconfiguration.
Prioritize positive tube anchorage and secure seating to prevent leaks from vibration. The hex socket feature on straight adapters simplifies tool-assisted assembly, reducing over-torque damage. Regularly inspect for wear, burrs on the tube ends, and ensure compatible tubing is used. The compact design also helps minimize space constraints, enabling easier field maintenance and faster part replacement when needed.
