The FERGUSON ENTERPRISES 20201802 is a genuine OEM replacement drain tube designed for use in condensate drainage systems found in residential and light commercial HVAC equipment. Drain tubes carry condensate water away from the evaporator coil or heat exchanger to a drain pan or external drain line, preventing moisture buildup that can lead to equipment damage or mold growth. This part measures 1 inch in length and 1 inch in width, making it a direct-fit replacement for systems requiring this specification. Licensed HVAC technicians typically install this component during routine maintenance or when a drain tube shows cracking, clogging, or deterioration.
This drain tube is suited for residential and light commercial HVAC systems where condensate management is a critical part of system performance. It is commonly installed in split-system air conditioners, heat pumps, and gas or electric furnaces with cooling coils. Proper condensate drainage helps maintain system efficiency and prevents water damage to surrounding structures and equipment components.
Designed as an OEM-style replacement drain tube for HVAC systems requiring this specific part number. Confirm fitment against the equipment model number and service manual before installation.
Installation should be performed by a licensed HVAC technician. Before replacing the drain tube, shut off power to the unit at the disconnect switch or breaker and verify the system is de-energized. Inspect the surrounding drain pan, drain line, and condensate trap for blockages or damage while the unit is open. Follow all applicable local mechanical codes during service.
