1 inch Carbon Steel 400G Gas Press Coupling with Stop Press x Press

1 Inch Carbon Steel 400G Gas Press Coupling with Stop – Press x Press

The 1" carbon steel gas press coupling with integral stop is designed for joining carbon steel piping in fuel gas distribution systems. Rated for 400G applications, this fitting is engineered for use in non-potable fuel gas systems such as natural gas and propane in residential, commercial, and industrial environments.

Engineered for Gas System Integrity

This press coupling provides a permanent, flame-free connection method and features a built-in stop to control insertion depth. It complies with relevant performance and safety standards for carbon steel gas press systems. Key technical specifications include:

• ✅ Carbon Steel Body – Manufactured from ASTM-compliant carbon steel, providing excellent tensile strength and resistance to deformation under system pressure.
• ✅ EPDM Sealing Element – Factory-installed HNBR sealing rings are suitable for fuel gas and petroleum-based vapors; not intended for potable water use.
• ✅ Press x Press Configuration – Compatible with standard press tools using properly sized jaws; includes stop bead for proper pipe alignment.
• ✅ Pressure Rating – Rated up to 125 psi for fuel gas applications, per applicable standards (CSA B137, ANSI LC4/CSA 6.32, ICC-ES PMG listing).

Contractor Advantages

Ideal for new installations or retrofits where open flame is restricted or not practical. This press coupling reduces labor time and mitigates fire hazards during installation:

• ✅ No Flame Required – Eliminates hot work permits and reduces site disruption.
• ✅ Consistent Sealing – Dual press ends with elastomeric gaskets ensure uniform compression and leak resistance.
• ✅ Clean Assembly – Maintains system cleanliness with minimal prep; ideal for overhead, wall cavity, or confined space work.

Installation Parameters

Verify pipe ends are cut square and free of debris. Insert piping fully to the stop, align properly, and complete press with manufacturer-recommended tools. Always check press profiles for compatibility. System testing should be conducted per local code and governing fuel gas installation standards.

Typical Applications

Used in low-pressure gas piping for boilers, furnaces, water heaters, commercial cooking equipment, and other fixed fuel-burning appliances. Suitable for indoor and outdoor above-ground installations where carbon steel piping is approved for use.

Code Compliance Note

Fitting complies with ICC PMG, ANSI LC-4, and other national standards governing press-connect fuel gas systems. For use with Schedule 5–40 carbon steel pipe in fuel gas and compressed air applications where permitted by code.

The 1 Inch Carbon Steel 400G Press Coupling with Stop delivers field-proven reliability and flame-free installation in fuel gas systems. Designed for contractors requiring performance, safety, and labor efficiency, it’s a key component in scalable gas distribution systems for commercial and residential builds.
