Lennox 14M89 Pressure Switch Tubing Kit

The Lennox 14M89 Pressure Switch Tubing Kit is a replacement product to join a pressure switch to other components of Lennox HVAC equipment, mainly furnaces. Constructed from nylon, this kit offers the correct tubing for pressure switch operation in a long-lasting material. The tubing forms a closed system between the pressure switch and the vent pipe or the gas manifold in your furnace. This helps enable the switch to determine changes in air pressure, which are so essential for the proper functioning of the switch.
