Do not forget to
carefully evaluate the pictures or match your OEM Part Number. As some Vehicle
come with more then one option. For Example. please make sure you have rear A/C or no rear on your SUV, they will have different lines. If you have any questions please send a

Omega Environmental Technologies Hose
Assemblies tubes and fittings match OE design combining the uses of both steel
and aluminum. All hose assemblies meet tensile standards for SAEJ51 and IMACA
312 for R12 and SAEJ2064 for R134a.
Here are the three main
hose in the ac system.
Suction Line - Is also referred to as the
low-pressure vapor line. In an Expansion valve configuration the line connects
the evaporator outlet to the compressor inlet. In an orifice tube configuration
the line the line connects from the accumulator to the compressor inlet. Either
way suction line always connects to the compressor.
Discharge line. Also referred to High-pressure
discharge line, connects the compressor outlet to the condenser inlet. This
goes the same for both expansion and orifice tube configuration.
Liquid line - Is also referred as the
high-pressure liquid line. In an Expansion valve configuration, the line
connects on the condenser outlet to the receiver-drier inlet. It also connects
the receiver-drier outlet to the evaporator metering device inlet. In an
orifice tube configuration, the line connects on the condenser outlet to the
evaporator inlet with the orifice tube inside the liquid line.
When to replace hose
assemblies?
Hose Assemblies and lines should be replace any time they are
damage. When damaged they leak refrigerant and oil which can cause oil
starvation on the A/C Compressor. Resulting in internal damage or premature
clutch wear. So it’s always recommended to replace the accumulator or drier
every time a hose is being repaired.
