2 inch Carbon Steel 477 1G Gas Press Flange Adapter

2 Inch Carbon Steel Gas Press Flange Adapter – ANSI-Class Interface for Press-Fit Gas Systems

The 2 inch Carbon Steel Gas Press Flange Adapter is engineered to provide a secure, code-compliant transition between press-connected carbon steel piping and ANSI Class 150 flanged system components. Designed for fuel gas applications, this adapter offers high mechanical strength, consistent sealing, and simplified installation in both commercial and industrial gas distribution systems.

System Compatibility and Mechanical Performance

This fitting is manufactured from carbon steel with a zinc-plated exterior for enhanced corrosion resistance in non-condensing gas environments. The press end is compatible with standard TH- or V-profile jaws and includes a factory-installed yellow HNBR or EPDM sealing element rated for natural gas and propane service. The flange face aligns with ANSI B16.5 Class 150 bolt patterns, allowing integration with meters, valves, regulators, or other flanged components.

• ✅ Material: Carbon steel with corrosion-resistant zinc coating
• ✅ Sealing Element: Factory-installed gas-rated HNBR or EPDM, compliant with ANSI LC-4 / CSA 6.32
• ✅ Flange Standard: ANSI B16.5 Class 150 bolt pattern with flat-face or gasket-ready sealing
• ✅ Connection Type: Press x Flange, suitable for flame-free installation
• ✅ Visual Leak Detection: Designed to visibly indicate unpressed joints during pressure testing

Technical Specifications

• Nominal Size: 2 inch
• Max Operating Pressure: 125 psi (fuel gas applications)
• Temperature Range: -40°F to 180°F (based on seal material)
• Compliance: Conforms to ANSI LC-4 / CSA 6.32 and NFPA 54 (National Fuel Gas Code)

Application Areas

Commonly used in fuel gas infrastructure, this flange adapter enables secure press-to-flange transitions in rooftop equipment connections, meter manifolds, commercial appliances, mechanical rooms, and boiler systems. It supports system modularity, maintenance access, and rapid equipment changes while maintaining pressure integrity.

Installation Considerations

Ensure proper pipe preparation (cutting, deburring, and depth marking) before pressing. Use compatible press tools and jaws to achieve full compression of the sealing element. Flange bolts must be torqued according to manufacturer or gasket specifications to ensure a uniform seal. Leak testing must be performed with inert gas or air, following local code requirements.

Material Insight

Carbon steel press fittings offer high tensile strength and dimensional stability, making them suitable for gas systems where mechanical reliability and flame-free installation are priorities. Zinc plating extends the service life by mitigating surface corrosion from environmental exposure.

The 2 Inch Carbon Steel Gas Press Flange Adapter is a reliable solution for integrating press systems with flanged connections in gas piping applications. Its compliant design, robust construction, and ease of installation make it ideal for contractors working on modern gas infrastructure projects.
