Norgren M02250406 Pneufit M Push-in Fitting - 4mm
Part Number: M02250406
Quick Summary
Norgren M02250406 Pneufit M Push-in fitting enables tool-free connections for compressed air systems. In compact layouts, traditional fittings struggle with space, sealing reliability, and tool-dependent assembly. Industry standards often emphasize CE compliance, IP protection, and SIL considerations for pneumatic components. The M02250406 design delivers reliable, quick sealing with pre-applied thread sealant and a compact form factor. This makes maintenance faster and operations more predictable, especially in automation lines that rely on push-in connectors. With a nickel-plated brass body, nitrile seals, and a releasable grab ring, it resists corrosion and contamination. Choosing Pneufit M translates to lower downtime, longer lifespans, and clearer ROI for pneumatic system upgrades.

FAQs
The M02250406 Pneufit M Push-in fitting is designed for 4 mm outer diameter tubing and M6 port threads, supporting compressed air systems from 0 to 10 bar. It accepts nylon or polyurethane tubes (8.5–9.5 durometer) with a releasable stainless-steel grab ring for secure, reversible connections, and it uses a pre-applied thread sealant for rapid sealing.
This fitting provides tool-free, push-in assembly that minimizes installation time in cramped panels. Internal and external hex features on straight fittings allow easy tightening with standard wrenches, while mounting holes on the union fittings offer flexible mounting options for compact piping layouts.
Yes, with a tough PBT body, nickel-plated brass components, and nitrile seals, the assembly is designed for durability in demanding environments. Its operating range up to 10 bar and the corrosion resistance of the brass body support reliable performance in continuous-duty circuits.
Key features include silicone-free U-packing for contamination control, pre-applied thread sealant for rapid, leak-free seals, and a releasable grab ring that maintains a secure grip on 4mm tubing. Together, these reduce leakage risk and extend service life in automated lines.
