1 inch Carbon Steel Gas Press Union 4733 G Press x Press

1" Carbon Steel Press Union for Natural Gas and Fuel Gas Systems

The 1" Carbon Steel Press Union is manufactured for use in Schedule 10 and Schedule 40 carbon steel piping systems. It is engineered to support secure mechanical connections in gas distribution networks where press technology is preferred over threaded or welded methods.

This union features press-to-connect ends that provide a flameless installation method, reducing fire risk and labor time on-site. The carbon steel body is corrosion-protected with a zinc-nickel coating to extend service life in gas line applications. Compatible with ASTM A53, A106, A135, and A795 steel pipes.

Technical Specifications

• Nominal Size: 1 inch
• Connection: Press x Press
• Material: Carbon Steel (zinc-nickel coated)
• Sealing Element: HNBR (suitable for fuel gas and air)
• Operating Temperature: -40°F to 180°F

Design Features

• Fabricated for use in carbon steel piping systems carrying natural gas, propane, and fuel gas mixtures
• Union body allows for system disassembly at the joint for maintenance or reconfiguration
• Dual press connections minimize installation time and reduce leak risk compared to threaded connections
• Visual press indicator confirms secure connection after crimping
• Lead-free and fire-safe installation method – no solder, flux, or open flame required

Application Areas

Used in commercial and residential gas piping systems including:

• Natural gas distribution for heating systems
• Fuel gas lines for boilers and furnaces
• Propane systems in mixed-use buildings
• Retrofitting and maintenance in confined spaces

Installation Notes

This fitting requires a compatible press tool equipped with jaws or rings certified for carbon steel press fittings. Pipe must be cut square, deburred, marked to insertion depth, and fully inserted before pressing. Sealing integrity depends on proper alignment and press force. For gas systems, verify local code compliance and manufacturer instructions.

The 1" Carbon Steel Gas Press Union offers a reliable, code-compliant method for joining steel pipe in fuel gas systems, significantly improving speed and safety of installation over traditional joining methods.
