Premium Material: Furnace pressure switch hose is made of industrial-grade silicone rubber, offering outstanding heat resistance up to 482°F (250°C) along with excellent corrosion resistance, aging resistance, and pressure durability
Reliable Function: Silicone rubber hose effectively replaces aged, hardened, clogged, or cracked tubing, allowing the pressure switch to accurately detect furnace air pressure again, thereby ensuring proper ignition and safe operation
Standard Specifications: Designed with a standard 3/16" inner diameter and 19" length, the hose offers wide compatibility. The flexible silicone material bends easily without collapsing or kinking, ensuring smooth airflow and consistent performance across various furnace pressure control systems
Easy Installation: Both ends of the silicone hose feature a plug-and-connect design for quick attachment to the pressure switch and furnace port—simple enough for beginners to replace. The package includes 2 fixed clips, which secure the hose in place and help maintain stable air pressure
Wide Compatibility: This hose is engineered for a variety of gas furnace pressure switch systems and is compatible with Rheem, Ruud, and Weatherking furnace models. It directly replaces 79-21491-83
