Description
Lennox 14K65 Suction Accumulator Overview
The Lennox 14K65 is an OEM suction accumulator designed to protect the compressor in Lennox HVAC and refrigeration systems. Featuring a 1-3/8″ ODF (Outside Diameter Flare) suction connection, this accumulator intercepts liquid refrigerant and oil before it can enter the compressor, preventing liquid slugging and extending compressor service life.
Key Features
- OEM Lennox replacement part — engineered for precise fit and performance in compatible Lennox systems
- 1-3/8″ ODF suction connection for secure, leak-free installation
- Protects the compressor from liquid refrigerant slugging and oil flooding
- Separates liquid refrigerant from vapor, allowing only dry gas to enter the compressor
- Durable construction built to withstand the demands of residential and light commercial HVAC applications
- Helps maintain system efficiency and reliability over the long term
Why Use a Suction Accumulator?
A suction accumulator is a critical refrigeration system component installed in the suction line between the evaporator and the compressor. It acts as a reservoir and separator, catching any liquid refrigerant or oil that may carry over from the evaporator. By ensuring only refrigerant vapor enters the compressor, the accumulator prevents compressor damage caused by hydraulic shock (liquid slugging), which can result in costly repairs or full compressor replacement.
