The NORDYNE INTERTHERM 263967 is a pressure switch tube used in gas furnace systems to connect the pressure switch to the inducer or collector box. This tube carries the negative pressure signal that allows the pressure switch to verify proper inducer operation before the furnace control board allows ignition to proceed. At 30 inches in length, it provides adequate reach for the routing paths found in typical residential furnace installations. HVAC technicians install this part during pressure switch diagnostics, tubing replacement, or inducer assembly service.
This pressure switch tube is suited for residential gas furnace applications where the original tube has cracked, collapsed, or become disconnected. It is a direct-fit replacement designed to restore proper pressure sensing function in furnaces manufactured under the Intertherm, Nordyne, Revolv, and Coleman brand families. Proper pressure switch tube function is critical to furnace lockout prevention and safe ignition sequencing.
Designed as a replacement pressure switch tube for gas furnaces produced under the Intertherm, Nordyne, Revolv, and Coleman brand families. Verify routing length and fitting diameter against the original tube before installation.
A licensed HVAC technician should install this part. Shut off power to the furnace at the disconnect or breaker before beginning any service work. Inspect both the pressure switch port and the inducer outlet port for debris or moisture before seating the new tube. Confirm the tube is fully seated and free of kinks after installation before restoring power and testing furnace operation.
