Chevrolet C1500 A/C Hose

Choosing An A/C Hose Assembly

An A/C hose connects components in the sealed refrigerant circuit. Choose the line for the section being repaired: a suction line, a discharge line, a liquid line or a combined assembly. The fittings, routing and refrigerant service must match the installed system; a coolant hose is not a substitute.

A-Premium offers individual lines as well as selected manifold assemblies and multi-line sets. Check the listed components to determine whether a package covers the line that needs replacement.

Suction, Discharge And Liquid Lines

The suction side carries refrigerant vapor from the evaporator toward the compressor. The discharge side carries hot, pressurized refrigerant from the compressor toward the condenser. A liquid line carries refrigerant from the condenser side toward the metering device; the route can include other components depending on the system.

The sections operate in different parts of the circuit and use application-specific connections. Match the intended line rather than substituting a hose solely because its end fittings look similar.

A/C Hose Fittings And Routing

Many assemblies combine shaped metal tubing with flexible hose. A line may also have a service port, a sensor connection, a branch or a mounting bracket. Compare these features with the original assembly so that all required connections remain available.

Route the replacement along its intended path and support it as specified. Contact with moving parts, sharp edges or hot surfaces can damage a line even when the end fittings initially seal.
