2 inch Carbon Steel 401G Gas Press Coupling with Stop Press x Press

2" Carbon Steel 401G Gas Press Coupling with Stop – Engineered for High-Performance Gas Distribution

The 2" Carbon Steel 401G Gas Press Coupling with integrated stop is manufactured for gas-tight reliability in high-demand distribution systems. Designed for use with compatible press tools, this fitting provides consistent sealing integrity and mechanical strength across a wide range of installations.

Produced from corrosion-resistant carbon steel, the 401G series coupling meets strict code requirements for fuel gas service. Its stop feature assists with precise pipe insertion depth, reducing installation error and enhancing alignment consistency during press cycles.

Functional Design Benefits

Engineered to minimize installation variability and support long-term gas system performance:

• ✅ Carbon Steel Construction – Suitable for fuel gas applications; meets ASTM and ANSI mechanical property standards.
• ✅ Factory-Applied Sealing Element – Pre-installed HNBR o-ring rated for gas service and high-temperature tolerance.
• ✅ Integrated Stop Press Feature – Promotes proper insertion depth and uniform sealing across connections.
• ✅ Pressure Tested – Factory tested for use in natural gas and propane systems; pressure ratings adhere to code-mandated limits.
• ✅ Press-Fit Configuration – Reduces jobsite labor and eliminates the need for threading or welding.

Key Specifications

• Nominal Size: 2"
• Material: Carbon Steel (zinc-plated for corrosion resistance)
• Seal Type: Yellow HNBR (gas-rated)
• Application: Fuel gas piping (natural gas, LP, and mixed gas systems)
• Joining Method: Press connection compatible with standard press tools and jaws

Installation Considerations

This press coupling should be installed by qualified personnel familiar with gas system requirements and certified press-fit tool use. Key practices include:

• Pipe must be properly deburred and marked for visual inspection prior to pressing.
• Verify o-ring integrity before press cycle; avoid contact with petroleum-based sealants.
• Ensure press tools and jaws are manufacturer-approved and calibrated.

Post-installation pressure testing is required in accordance with local and national gas codes.

Typical Applications

This fitting is specified for use in fuel gas distribution systems for both commercial and residential construction. It is suitable for new installations, retrofits, and phased system upgrades where press technology enhances efficiency and safety.

Material Insight

Carbon steel gas press fittings provide robust mechanical properties, high tensile strength, and thermal resistance required for gas transport under operating pressure. Zinc coating enhances corrosion resistance during storage and after installation.

The 2" Carbon Steel 401G Gas Press Coupling with Stop is designed to deliver code-compliant performance and installation consistency in gas piping systems. Utilize press technology for time-efficient, secure gas line connections that meet inspection standards.
