1-1/4" Carbon Steel 411G Gas Press Tee – Carbon Steel Tee for Press-Fit Gas Systems

The 1-1/4" Carbon Steel 411G Gas Press Tee is a press-connect tee fitting designed for joining three sections of carbon steel pipe in fuel gas distribution systems. Manufactured from ASTM A420 carbon steel, this fitting is engineered for use with press tools and compatible jaws to create flame-free, mechanical joints that meet industry standards.

Product Specifications

• Material: Carbon Steel (ASTM A420)
• Size: 1-1/4 inch nominal (all three ends)
• Connection Type: Press-fit (gas-rated), suitable for use with carbon steel pipe
• Sealing Element: HNBR (Hydrogenated Nitrile Butadiene Rubber), yellow, approved for gas service
• Operating Pressure: Up to 125 psi (gas applications)
• Temperature Range: -40°F to 180°F for HNBR seals
• Standards: Conforms to ASME B16.14, IAPMO/ANSI LC 4, and ICC-ES PMG-1218 for fuel gas distribution

Application and Use

This press tee is specified for use in low-pressure natural gas and propane installations. Typical applications include branch connections in horizontal or vertical gas piping systems in residential, commercial, and light industrial construction. Compatible with approved carbon steel piping systems and installation tooling.

Installation Considerations

Press connections must be made using manufacturer-approved press tools and jaws compatible with the fitting profile. Verify that pipe ends are cut square, deburred, and marked for insertion depth. HNBR seals must be clean, undamaged, and properly seated. Not suitable for underground applications unless otherwise protected.

Performance Benefits

• ✅ Flame-Free Installation: Press technology eliminates the need for hot work permits or fire watch.
• ✅ Time-Efficient: Reduces labor time compared to threading or welding, improving jobsite productivity.
• ✅ System Integrity: Factory-installed sealing elements ensure consistent compression and reduced leak risk.
• ✅ Field Proven: Rated for use in fuel gas systems and certified under established national standards.
• ✅ Corrosion Protection: Exterior surfaces often include electroplated zinc coating for added corrosion resistance (confirm product-specific details).

Compliance and Testing

This fitting meets the performance requirements of CSA LC 4, IAPMO/ANSI Z223.1 (NFPA 54), and UPC-listed for fuel gas use. It is tested to ensure mechanical strength, long-term seal integrity, and resistance to vibration and thermal cycling.

Notes

Do not install in systems exceeding temperature or pressure limitations of HNBR sealing elements. Use only with compatible pipe and press tools as specified by the system manufacturer.

The 1-1/4" Carbon Steel 411G Gas Press Tee offers a professional-grade solution for mechanical gas piping connections, combining speed of installation with code compliance and system reliability.
