- The Flexmaster NovaVent 2NVRHA4 4-Inch Stainless Steel Appliance Adapter is a commercial-grade special gas vent component engineered specifically to mate directly onto the factory collar of Reznor UD series gas-fired unit heaters.
- Expertly fabricated from high-grade 440 super-corrosion-resistant stainless steel, this single-wall adapter incorporates an integrated mechanical back-flow preventer that stops hazardous flue exhaust from reversing travel back toward indoor spaces.
- Rated for Category II, III, and IV positive-pressure ventilation lines, the 2NVRHA4 features NovaVent's patented pre-installed internal gasket seal system, allowing HVAC technicians to lock down a completely gas-tight, tools-free connection without the need for high-temperature silicone sealants.
