1-1/2 inch x 1-1/4 inch Carbon Steel 403G Gas Press Reducing Adapter Press x Female

1-1/2" x 1-1/4" Carbon Steel 403G Press Reducing Adapter – Engineered for High-Integrity Transitions

The 1-1/2" x 1-1/4" Carbon Steel 403G Reducing Adapter is designed for mechanical system applications requiring pipe size transitions within gas or hydronic networks. Constructed from durable carbon steel and manufactured to stringent dimensional tolerances, this press adapter enables secure, code-compliant connections without the need for heat or threading.

Engineered for installation in commercial, industrial, and large-scale residential projects, this fitting supports streamlined workflow in new construction and retrofit conditions alike. The press ends are compatible with standard carbon steel press tools, ensuring consistent results in the field while minimizing downtime and labor costs.

Contractor-Grade Advantages

• ✅ Dimensional Accuracy – Fabricated to maintain tight engagement with press jaws, reducing the risk of installation failure.
• ✅ High-Strength Carbon Steel – Provides structural integrity under elevated operating pressures and mechanical load conditions.
• ✅ Press x Press Configuration – Allows for flame-free, time-saving installations in accordance with safety codes.
• ✅ Surface Protection – Treated exterior offers resistance against corrosion and environmental degradation.
• ✅ Standards Compliance – Meets applicable criteria for press fittings used in gas and mechanical piping systems.

Installation Notes

This adapter is intended for use with carbon steel press systems and should be installed using manufacturer-approved tooling and calibration procedures. Ensure proper pipe preparation, insertion depth, and alignment prior to pressing. Thread sealants are not required with press connections but may be specified in mixed-system interfaces depending on application requirements. All installations must adhere to local mechanical, fuel gas, and plumbing codes.
