The Lennox 92L82 is a genuine OEM pressure switch tubing component engineered specifically for Lennox HVAC systems. This tubing serves as the critical connection between the pressure switch and the system’s draft inducer or collector box, enabling accurate differential pressure sensing that keeps your furnace or air handler operating safely and efficiently.
Why OEM Tubing Matters
Using the correct OEM-specified tubing ensures a proper, airtight seal between the pressure switch port and its sensing point. An improper fit or aftermarket substitute can lead to false pressure readings, nuisance lockouts, or — more critically — failure to detect a blocked flue or failed inducer motor. The Lennox 92L82 is manufactured to exact Lennox tolerances, giving technicians confidence in every installation.
