1-1/4 inch x 1 inch Carbon Steel 418G Gas Press Reducing Fitting Male x Press Carbon Steel

1-1/4" x 1" Carbon Steel Gas Press Reducing Fitting – Press x Press

This 1-1/4" x 1" carbon steel press reducing fitting is manufactured to transition between nominal pipe sizes in gas distribution systems. It is designed for use in fuel gas and low-pressure natural gas applications using press-connect technology compatible with carbon steel piping systems.

Fabricated from ASTM A420 carbon steel and equipped with EPDM sealing elements rated for gas service, this fitting supports reliable, flame-free installation. The press ends feature grip rings and sealing elements to create a secure mechanical joint without threading or welding.

Technical Specifications

• Material: ASTM A420 carbon steel
• Connection Type: Press x Press (V-profile)
• Size: 1-1/4" CTS x 1" CTS
• Sealing Element: Yellow HNBR (Hydrogenated Nitrile) O-rings for fuel gas compatibility
• Pressure Rating: Up to 125 PSI (gas applications)
• Temperature Range: -40°F to 180°F
• Standards Compliance: ANSI LC 4/CSA 6.32; ICC-ES PMG; IAPMO listed

Application Areas

Commonly installed in natural gas and propane piping systems, including:

• • Commercial and multi-family fuel gas infrastructure
• • HVAC equipment connections (heaters, boilers, dryers)
• • Retrofit and tenant improvement work where flame-free installation is required
• • Utility gas manifolds and line size transitions

Installation Guidelines

Use only with approved carbon steel tubing. Ensure pipe ends are cut square, deburred, and marked for insertion depth. Always verify O-ring integrity before pressing. Install with manufacturer-approved press tools fitted with the correct jaw profile. Press connections are permanent and should be tested in accordance with local gas codes prior to system commissioning.

Material Insight

Carbon steel press fittings are favored in gas distribution systems for their pressure capacity, mechanical strength, and corrosion resistance when installed in dry or inert gas environments. Press-connect technology offers time savings and improved jobsite safety by eliminating open-flame joining methods.
