Norgren M02250403 Pneufit M Adaptor - External hex
Part Number: M02250403
Quick Summary
Pneufit M adaptor offers tool-free, push-in quick-connect for compressed-air lines in compact equipment. In tight spaces, threaded fittings slow assembly and risk leaks; this adaptor simplifies installation with a secure push-in seal. Designed to align with common industry standards and safety practices, it supports CE compliance and SIL-ready integration in certified systems where applicable. Using this solution reduces assembly time, improves reliability, and lowers total cost of ownership, while maintaining compatibility with 4 mm tubing and M3 threads.

Feature: Tool-free push-in Pneufit M adaptor enables fast, tool-free assembly with secure connections. Business Impact: Reduces installation time and labor costs, minimizes live-test downtime, and improves first-pass quality in production lines. Application: Ideal for compact automation panels and space-constrained pneumatic networks where quick-field assembly is critical. The 4 mm port and M3 thread support standard 4 mm tubing, enabling rapid integration into existing layouts. Feature: Releasable stainless-steel grab ring grips nylon or polyurethane tubing. Business Impact: Provides secure retention during vibration and allows quick release for service or reconfiguration, reducing maintenance time and risk of line loss. Application: Suitable for pneumatic circuits in robotics and packaging where frequent line changes occur. Feature: Nickel-plated brass components for corrosion and contamination resistance. Business Impact: Extends service life in harsh environments, lowers replacement cycles, and improves system reliability in long-life deployments. Application: Harsh industrial environments and outdoor installations where climate and cleaning processes can impact fittings. Feature: Pre-applied thread sealant on taper threads delivers immediate, reliable sealing without extra joint preparation. Business Impact: Cuts field assembly time, minimizes leak-related downtime, and improves overall line efficiency. Application: Field installations and retrofit projects where speed and reliability are essential. Feature: Internal and external hexes on straight fittings improve grip and torque control during assembly. Business Impact: Reduces tool slippage, improves repeatability, and supports consistent installation quality across technicians. Application: Panels and manifolds with restricted access or low-clearance zones. Feature: Mounting holes on all union fittings enable straightforward mounting in compact spaces. Business Impact: Facilitates clean, vibration-resistant installations and streamlined routing of tubing and cables. Application: Modular automation architectures and quick-change configurations. Compatibility note: Works with PA2-0004100 and PA2-0004025C polyamide tubing (4 mm / 2.5 mm). This compatibility broadens applicability across common pneumatic lines and reduces part variety in assembly lines.

FAQs
Installation is straightforward and tool-free thanks to the push-in Pneufit M design. The adaptor uses a releasable stainless-steel grab ring for secure retention and quick release, with a pre-applied thread sealant for rapid, leak-free sealing on taper threads. Its 4 mm port and M3 thread align with common 4 mm tubing, reducing assembly time in constrained control panels.

Yes. It is designed for compact pneumatics with 4 mm tubing and M3 threads, offering tool-free installation and a space-saving straight fit. The silicone-free U-packing and pre-applied sealant enhance leak prevention, while the nickel-plated brass components provide corrosion resistance. It pairs well with Pneufit M manifolds and automation panels needing fast, reliable connections.
Norgren designs Pneufit M fittings to support common industry practices and safety objectives. While the data sheet references general compliance and regional standards, users should consult the official datasheet for explicit certification details (for example CE or SIL suitability) and ensure installation within your certified system. Always verify local regulatory requirements and manufacturer guidance.
The push-in design reduces installation time and labor costs, while pre-applied thread sealant minimizes sealing steps and leak-related downtime. Stainless grab rings and nickel-plated brass construction enhance reliability in vibration-prone environments, lowering maintenance frequency. Overall, faster assemblies, reduced maintenance, and longer service life translate into lower total cost of ownership in automated pneumatic lines.
