Product Details

Description

This genuine Lennox pressure switch tubing is a critical component for the safe and efficient operation of residential and commercial gas furnaces. As a vital link in the air-proving system, this flexible hose transmits pressure signals from the draft inducer motor or collector box to the air pressure switch. It ensures the system detects proper airflow before allowing the ignition process to begin, preventing hazardous operation. Over time, original tubing can become brittle, cracked, or clogged, leading to furnace ignition failure or intermittent shut-offs. Replacing damaged tubing restores accurate pressure sensing and helps maintain the peak performance of your heating system.
