1-1/4 inch Carbon Steel 404G Gas Press Adapter Press x Male

1-1/4" Carbon Steel Gas Press Adapter – Apollo PowerPress 404G Series

The Apollo 404G 1-1/4" gas press adapter is part of a press-connect carbon steel fitting system designed for use in fuel gas distribution piping. This adapter provides a transition from press connection to male NPT and is engineered for high-integrity gas systems operating under ANSI LC 4 certification guidelines.

Manufactured from ASTM A105 carbon steel, this fitting features a corrosion-resistant zinc-nickel coating and an HNBR sealing element, making it suitable for a wide range of non-potable fuel gas applications. The press ends are compatible with industry-standard press tools using approved jaws for carbon steel systems.

Installation Considerations

Install using compatible press tools with manufacturer-approved press jaws for carbon steel fittings. Ensure pipe ends are cut square, deburred, and clean. No threading or welding is required. The NPT end must be sealed with approved thread sealant or PTFE tape per jobsite requirements. Adapters must be supported in accordance with local codes and Apollo installation instructions.

Typical Applications

This fitting is intended for indoor and outdoor fuel gas systems, including natural gas and propane distribution in residential, commercial, and industrial settings. It is often used in appliance drops, meter set assemblies, rooftop piping, and boiler supply lines where mechanical press fittings offer speed and consistency over traditional threading.

Material and Performance Insight

Carbon steel press fittings provide a flame-free installation method for fuel gas lines. The use of HNBR elastomeric seals ensures chemical compatibility and temperature stability in accordance with fuel gas system requirements. Zinc-nickel coatings further enhance corrosion resistance for exposed or humid environments.
