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

2" Carbon Steel Press Union – Designed for Gas Applications

The Apollo PowerPress 2" Carbon Steel Gas Press Union (Model 4733G) is engineered to meet the stringent requirements of natural gas and propane piping systems. It features a union-style connection with press-to-connect ends, allowing for quick disassembly without compromising safety or system integrity. Manufactured from ASTM A53/A106 carbon steel, it offers reliable performance in high-pressure, non-potable gas installations.

This press union is ideal for commercial and industrial gas distribution systems. It incorporates a yellow HNBR sealing element specifically formulated for gas service and includes a visual indicator to confirm proper press installation. By eliminating the need for threading or welding, it significantly reduces installation time and eliminates hot work hazards on site.

Key Features

• Material: Black carbon steel (ASTM A53/A106 Grade B)
• Connection Type: Press x Press with union center connection
• Sealing Element: Yellow HNBR for gas compatibility
• Pressure Rating: Up to 200 PSI
• Temperature Range: -40°F to 180°F
