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

2" x 1-1/4" Carbon Steel Gas Press Reducing Adapter – Built for High-Integrity Transitions

The 2" x 1-1/4" Carbon Steel Gas Press Reducing Adapter is engineered for gas distribution systems requiring secure, size-reducing connections between press-compatible carbon steel piping. Manufactured from high-strength 403G-grade carbon steel, it supports mechanical reliability under pressure while facilitating code-compliant installations in commercial, industrial, and multi-residential applications.

This adapter is suitable for systems operating under regulated conditions and requiring uniform press engagement. Its machined press ends and dimensional consistency help reduce failure points and support long-term system stability, especially in high-demand environments.

Performance Characteristics

• ✅ Material Grade: Fabricated from carbon steel (403G) to meet mechanical and thermal stress requirements.
• ✅ Secure Fit – Designed with tight manufacturing tolerances to ensure proper alignment and press tool engagement.
• ✅ Pressure-Rated – Suitable for gas systems requiring consistent sealing under elevated operating pressures.

Installation Requirements

Use only with manufacturer-approved carbon steel press tools. Pipe ends must be cut square, deburred, cleaned, and inserted to the proper depth before pressing. This fitting does not require thread sealant or plumber’s tape. All installations must follow local fuel gas and mechanical codes.

Technical Specifications

• Material: 403G Carbon Steel
• Size: 2" x 1-1/4"
• Connection Type: Press x Press (female)
• Service Application: Gas distribution (natural gas, LP gas, and approved fuel systems)

Application Scope

Commonly installed at size transitions in pressurized gas systems, including branch lines, appliance connections, riser transitions, and trunk-to-subheader conversions. This adapter is used in both new system designs and retrofit installations where precision and mechanical durability are required.

Material Compliance Note

Carbon steel press fittings are widely specified for their strength-to-weight ratio, corrosion resistance with proper coating, and compatibility with press-join installation techniques. In gas applications, press fittings reduce risk associated with heat-based connections and support code-mandated safety measures.
