Norgren M02260405 Pneufit M Push-in Fitting - 4mm M5
Part Number: M02260405
Quick Summary
Norgren Pneufit M fittings enable fast, tool-free connections in compressed air lines for compact automation assemblies. In tight panels, engineers struggle with space, tools, and leak-prone joints that slow production. Certification status for this part isn’t listed here; in practice, CE marking, IP-rated protection where applicable, and SIL considerations are common checks in pneumatic installations. The design—silicone-free U-packing, nickel-plated brass, and a stainless-grab ring—delivers reliable sealing and long life, while pre-applied thread sealant speeds assembly. When paired with compatible 4 mm PA tubing, this adaptor supports rapid, scalable, and cost-efficient air-system upgrades for automotive, packaging, and automation lines.

FAQs
M02260405 accepts 4 mm outer diameter tubes. For PA tubing options, use PA2-0004100 (100 m) or PA2-0004025C (25 m), both standard polyamide tubes compatible with Pneufit M fittings. Ensure the tube O/D matches the 4 mm port size and avoid tubing with excessive hardness or coatings that hinder insertion.
Verify the taper thread surfaces are clean and dry, apply the pre-sealed taper threads as designed, insert the 4 mm O/D tube fully until seated, and tighten using the internal hex on the fitting body to the manufacturer’s recommended torque. The silicone-free U-packing helps prevent silicone contamination and promotes rapid sealing.
Yes, the Pneufit M adaptor is designed for robust industrial use with a corrosion-resistant nickel-plated brass body and nitrile seals. While operating temperature and pressure are defined (-20 to 60 °C, 0 to 10 bar), verify system vibration levels and enclosure conditions to ensure full reliability in your specific application.
For regulated environments, verify applicable certifications such as CE marking, IP protection where applicable, and any SIL-related approvals required by your safety standards. This data sheet does not list specific marks; confirm with the supplier or your compliance team to ensure alignment with your facility’s regulatory requirements.
The tool-less push-in design reduces installation time and labor costs, while reliable silicone-free sealing minimizes leak-related downtime. Combined with long service life and compatibility with standard PA tubing, this can shorten commissioning, lower maintenance interruptions, and improve overall line efficiency and uptime in automation, packaging, or automotive assembly lines.
