Lennox 14K65 Suction Line Accumulator 1-3/8" ODF

The Lennox 14K65 is a suction line accumulator designed to prevent liquid refrigerant from entering the compressor, protecting critical HVAC system components from potential damage. This device collects excess refrigerant and ensures only vapor returns to the compressor, which is essential for maintaining proper system operation and compressor longevity.

Key Features:

• Features a 1-3/8" ODF (flare) connection for secure attachment to system piping
• Protects compressor from liquid slugging and bearing damage
• Meters refrigerant and oil back to compressor at controlled rates
• Essential for heat pump systems during cycle reversal and defrost operations
• Genuine Lennox OEM replacement part

Suction accumulators are particularly important in heat pump applications where refrigerant flooding can occur during heating/cooling cycle switching, defrost cycles, and low ambient operation. This component installs in the suction line between the evaporator and compressor, providing critical system protection and reliable performance.
