Lennox 98L78 Tubing
The Lennox 98L78 Tubing is a critical OEM replacement kit used for establishing airtight connections between furnace pressure switches and intake/exhaust components. This high-temperature pressure switch square tubing is engineered to withstand the rigorous thermal cycles found in modern condensing gas furnaces. As a veteran-grade HVAC replacement part, this kit features an approximate 3/16-inch ID (inner diameter), ensuring accurate pneumatic signals are sent to the controller to verify proper combustion air pressure and flue venting.
The Lennox 98L78 is a comprehensive 18-piece assortment that simplifies field repairs by providing multiple lengths: (6) 9-inch tubes, (6) 6-inch tubes, and (6) 2-inch tubes. This configuration allows technicians to replace LB-97803A components across a broad range of Lennox Elite and Merit series models, including the EL180, EL280, G40, and G50 frames. Using genuine OEM pressure switch tubing ensures consistent HVAC pressure switch configuration, preventing nuisance trips and system lockouts caused by cracked or brittle aftermarket lines.
