3/4 inch Carbon Steel Gas Press Union 4733 G Press x Press

3/4 Inch Carbon Steel Gas Press Union – Press x Press

The 3/4 inch carbon steel gas press union is engineered for use in fuel gas systems requiring high mechanical strength and leak-proof press connections. Manufactured from corrosion-resistant carbon steel, this union delivers consistent performance in both new construction and retrofit applications involving natural gas and propane piping systems.

Application and Performance Benefits

• ✔ Press Technology – Dual press ends compatible with standard press tools, reducing installation time and labor.
• ✔ Mechanical Strength – Built from carbon steel per ASTM specifications for structural integrity in pressurized systems.
• ✔ Gas-Approved Sealing Element – FKM sealing element ensures leak-tight performance in gas applications, with resistance to hydrocarbons and elevated temperatures.
• ✔ Field Service Efficiency – Allows system disassembly at the union without full demounting, aiding future maintenance.

Technical Specifications

• Size: 3/4 inch nominal pipe size
• Material: Carbon steel (ASTM A513 or equivalent)
• Finish: Zinc-plated or e-coated for corrosion resistance (verify based on product model)
• Connection Type: Press x Press union with union nut
• Sealing Element: FKM (Fluoroelastomer) for gas use
• Operating Pressure: Up to 125 psi (depending on system design)
• Temperature Range: -20°F to 250°F (FKM range)

Installation Requirements

Use with standard press tools and jaws sized for carbon steel press fittings. Ensure proper pipe deburring, insertion depth, and pressing per manufacturer guidelines. Only compatible with carbon steel tubing; do not mix with copper or stainless steel systems. Press fittings should be installed in accordance with NFPA 54, IFGC, and local fuel gas codes.

Common Uses

This press union is suitable for use in:

• Residential and commercial natural gas supply lines
• Propane distribution systems
• HVAC fuel gas hookups
• Retrofit projects requiring easy separation for servicing

Note on Material Suitability

Carbon steel press fittings must not be used in potable water or corrosive environments unless externally protected. Always ensure compatibility with the fluid and system materials.

The 3/4 inch carbon steel gas press union offers professional-grade performance for contractors needing a fast, secure, and serviceable gas fitting solution. Built to meet current safety and mechanical code standards, this component provides a reliable alternative to traditional threaded or welded connections in gas system assemblies.
