Suction Hoses (low side) attach from the compressor to the evaporator. Discharge (high side) attach from compressor to condenser. Liquid Lines attach condenser to evaporator. Manifold hoses are combinations of suction and discharges lines.
Features & Benefits:
Designed to meet/exceed OE fit, form and function
Durability and leak tested on every new design
Direct fit replacement
A/C Refrigerant Lines
The Discharge Line carries High Pressure Gas between the Compressor and Condenser
The Suction Line carries Low Pressure Gas from the Evaporator to the Compressor (sometimes through an Accumulator).
The Liquid Line carries High Pressure Liquid from the Condenser to the Evaporator (often through an Expansion Device).
Some assemblies combine two or all three lines together.
