1 inch Brass AutoFlare Gas Adapter with Steel Mount Flange Flange x Male

1 Inch Brass AutoFlare Gas Adapter with Steel Mount Flange – Built for Secure, High-Performance CSST Connections

The 1 inch Brass AutoFlare Gas Adapter with Steel Mount Flange is a purpose-built fitting for connecting corrugated stainless steel tubing (CSST) to fixed piping systems. Featuring an integral steel flange for stable mounting, this adapter supports safe and compliant gas line installations in both residential and commercial environments.

Engineered for Strength and Reliability

• ✅ Brass Body Construction: Precision-machined from lead-free brass, offering corrosion resistance and mechanical integrity under pressure.
• ✅ AutoFlare Technology: Creates a gas-tight metal-to-metal seal without gaskets; flare fitting compresses directly onto the CSST end for a secure connection.
• ✅ Steel Mounting Flange: Integrated flange allows secure attachment to framing, panel boxes, or rigid support surfaces to minimize tubing strain and meet code anchoring requirements.
• ✅ Threaded Outlet: Female NPT outlet enables transition to rigid pipe or threaded gas control valves.

Application-Specific Performance

• ✅ Nominal Size: 1 inch (CSST inlet x 1 inch FNPT outlet)
• ✅ Operating Pressure: Rated up to 5 psi for low-pressure fuel gas systems per ANSI Z223.1 (NFPA 54)
• ✅ Temperature Range: -40°F to 150°F
• ✅ Material Standards: Brass per ASTM B16 / NSF/ANSI 372 (lead-free compliant)

Installation Guidelines

Use only with listed CSST tubing. Ensure the tubing is cut cleanly and inserted fully into the adapter. Do not use sealant on the flare face. Apply approved gas-rated thread sealant to the NPT connection only. Secure the flange using appropriate mechanical fasteners to a fixed structure. Always leak-test the system after installation in accordance with local fuel gas codes.

Typical Use Cases

This adapter is used to terminate CSST runs and anchor connection points in gas piping systems. Typical applications include:

• Wall penetrations and appliance stub-outs
• Transition points between flexible and rigid gas piping
• Manifold systems or branch terminations

Did You Know?

Steel flanged CSST fittings are required in many jurisdictions to prevent joint movement and reduce vibration risks at connection points—an essential safety feature in seismic zones and commercial installations.

The 1 inch Brass AutoFlare Gas Adapter with Steel Mount Flange combines structural stability with secure gas sealing technology. It's a proven solution for professionals installing CSST systems that meet code, reduce strain, and ensure long-term performance.
