Reznor 120875 Gas Connector

The Reznor 120875 is a high-performance 3/4" X 36" flexible gas connector engineered specifically for industrial and commercial HVACR applications. As an OEM Reznor gas connector, this component ensures a perfect fit and reliable seal for high-BTU equipment, including Reznor TR, UDAS, and UDAP series unit heaters. The 36-inch length provides the necessary slack to absorb mechanical vibration and seismic movement, preventing stress fractures common in rigid piping systems. Constructed from corrugated stainless steel, it delivers superior corrosion resistance and maintains structural integrity in demanding mechanical rooms.

This 3/4-inch diameter gas line is optimized for high-volume gas flow, supporting unit sizes from 250 through 400 MBTUh without pressure drops. The flexible gas hose design simplifies installation in tight configurations where hard-piping is impractical. By utilizing this HVAC gas supply line, contractors ensure compliance with modern safety standards while streamlining the connection between the main gas manifold and the appliance regulator.

• Optimized Flow: The 3/4" diameter supports high-capacity natural gas and propane applications for large unit heaters.
• Vibration Dampening: Corrugated design absorbs equipment vibration, protecting the gas valve and internal manifold.
• Precision Fit: Genuine OEM replacement part ensures compatibility with Reznor TR and UDXC model series.
• Durability: Stainless steel construction resists chemical corrosion and environmental wear in utility spaces.

Is this connector suitable for high-pressure gas systems?
This connector is designed for standard low-pressure appliance connections; ensure your supply pressure is regulated to the equipment's nameplate requirements before installation.

Can the Reznor 120875 be used for both Natural Gas and Propane?
Yes, the materials and 3/4" fittings are compatible with both natural gas and liquid propane (LP) systems common in commercial heating.

Does this replace standard 1/2" flex lines?
This is a 3/4-inch heavy-duty connector. It should only be used if the heater's gas inlet and the supply line are sized for 3/4" NPT to ensure adequate fuel volume.
