A/C Hoses and Fittings for GMC

The A/C hoses and fittings in your GMC vehicle can wear out over time. In order to keep your air conditioning running at peak efficiency, seals must be tight. Worn parts and loose fittings lead to refrigerant leakage and ineffective air conditioning.

What kinds of A/C hoses does GMC use?

GMC uses standard air conditioning parts, which vary by model and build. Each part has specific marking on the side to indicate the type of liquid it can hold and transport. In addition to air conditioning, many vehicles use hydraulic hoses for other purposes, including brakes. Hydraulic power can be used in place of engine power to run the compressor. Hydraulic system hoses often look very similar to refrigerant hoses, but the two are not interchangeable. All hydraulic hoses carry specific labels to indicate their intended purpose. Wrong use of a hydraulic hose can lead to inefficient operation and dangerous tears. Here are the kinds of hoses you will see in your GMC vehicle.

  • Condenser and compressor lines: Sometimes made of metal, this line carries high-pressure refrigerant from the compressor to the condenser and then to the dryer. At this point in the cycle, compressed liquid may require hydraulic hose types. Hydraulic refers to liquids transported at very high pressure. In order to cool the air, refrigerant needs to be compressed into extremely hot hydraulic form at this stage.
  • Refrigerant or suction: This type carries liquid refrigerant and vapor back toward the compressor. While the rubber barrier hose looks very similar to hydraulic hoses, pressure requirements are very different.
  • Bundled hoses: In some models, you will find all or several A/C hoses bundled together. If one hose wears out, you may need to replace all hoses. This includes barrier and hydraulic hoses bundled together with fittings.
What kind of fittings does GMC A/C use?

Fittings refer to the metal connectors on the ends of refrigerant hoses. In most cases, fittings come attached to the hose, but you can also find fittings separately. Fittings are made of carefully shaped metal designed to crimp hose ends on both sides. In order to prevent leakage, fittings must be tightly attached to the hose, and fittings must also fit attached equipment. In some cases, you can replace loose fittings separately from other parts. If so, you will need to measure width along the outer diameter along with fitting length and shape. These measurements vary by GMC model.

How can you find the correct GMC parts?

Refrigerant and hydraulic hoses vary widely depending on GMC model. However, if you search by vehicle, you can be sure to find the correct parts.

  • Model, year, and trim: Because these parts vary depending on model, year, and trim, you will first want to narrow your search on this basis. For example, if you have a 2006 GMC Sierra 1500 Yukon XL, make sure to enter all of this information. Even within the same year and model, parts may vary depending on trim type.
  • Hose or fitting type: Next, you will want to look at the specific parts that need to be replaced.
  • Parts or kits: In some cases, you may be able to choose between individual parts or kits designed to replace all parts.
