1/2 inch Carbon Steel Gas Press Union 4733 G Press x Press

1/2 Inch Carbon Steel Gas Press Union – Press x Press Connection for Fuel Gas Systems

The 1/2 inch Carbon Steel Gas Press Union is a mechanical press fitting designed to join two sections of carbon steel pipe in natural gas or propane distribution systems. It enables secure, flame-free connections while maintaining accessibility for future maintenance or disassembly. The union incorporates a two-piece body and a central nut, allowing for a break point within rigid piping runs.

This press union is constructed from corrosion-resistant carbon steel and includes pre-installed HNBR sealing elements suitable for use in fuel gas service. The fitting is compatible with standard press tools and jaws designed for carbon steel systems with a press-profile connection interface.

Product Features and Application Benefits

• ✅ Press x Press Design – Joins two lengths of carbon steel pipe using a flame-free mechanical process, suitable for confined spaces and renovation work.
• ✅ HNBR Sealing Element – Factory-installed yellow O-ring rated for fuel gas applications in accordance with ANSI LC-4/CSA 6.32 standards.
• ✅ Lead-Free Carbon Steel Body – Manufactured in compliance with fuel gas system specifications and designed for resistance to mechanical and thermal stress.
• ✅ Demountable Joint – Union nut allows for mechanical separation without cutting pipe, simplifying service and retrofits.
• ✅ Pressure Rated – Suitable for use in systems up to 125 psi when installed per manufacturer and code guidelines.

Installation Guidance

Cut and deburr carbon steel pipe to appropriate length. Clean pipe ends and insert into the press union fitting until full seating is achieved. Mark insertion depth and confirm O-ring engagement. Use a compatible press tool with approved jaws to complete the mechanical connection. Do not apply heat or modify the fitting post-installation.

Common Applications

This union is specified for use in low-pressure natural gas or propane systems in residential, commercial, and light industrial settings. Typical installations include appliance branch lines, equipment shut-off loops, and mechanical rooms requiring maintenance access. It is suitable for both horizontal and vertical pipe orientations.

Material and Code Compliance

Constructed from lead-free carbon steel in compliance with ASME B16.51 and ANSI LC-4. Certified for use in fuel gas systems under UPC and IPC code requirements. Yellow HNBR sealing element identifies compatibility with fuel gas service.
