Air Conditioning Fittings

How Does a Car A/C System Work?

If you've ever driven around in the summer with a broken air conditioner in your vehicle, you know how important it is to keep cool while driving on hot days. Avoid sweating it out in the heat and let NAPA Auto Parts help you get the automotive A/C fittings and A/C parts you need for a successful system repair.

The air conditioning system in your vehicle has an evaporator that draws the warm air from your cabin over coils full of refrigerant, which absorbs heat. The resulting gas is then compressed and condensed to a point where it can radiate heat before the cycle starts all over again. For this system to work as designed and withstand drastic fluctuations in temperature and pressure, it must stay sealed. Otherwise, particulates and moisture can get in and degrade your vehicle's air conditioning from the inside. Ensuring the connections and fittings are secure and reliable is the best way to avoid those hot, miserable drives.

A/C Compression Fittings vs. Beadlock A/C Fittings

Along with gaskets and seals, your vehicle's A/C system can use anything from beadlock fittings, compression line fittings and couplers to expansion valves and gasket retainers. Beadlock-style fittings are designed with an O-ring end on one side and a locking steel collar on the opposite side that you will need to crimp onto the hose for a solid seal. Compression fittings feature a ring called a ferrule and a sleeve that slides over the ferrule. When tightened with a wrench, this compression fitting forms a reliable seal.

Recharging Your Car A/C at Home

Getting the cold air back in your vehicle can sometimes be as simple as doing a quick A/C recharge. If you've ever performed one of these straightforward jobs, you know that the A/C system in your vehicle has high- and low-pressure lines. A/C recharge kits use the low-pressure port, also known as the connector, to recharge your system with refrigerant. If the connectors on your A/C lines are worn or you find it difficult to get a good seal, it is possibly time to replace them. Remember, it's always a good idea to replace any worn hoses as well, but never repurpose old hoses from other vehicles or systems. A refrigerant hose is designed specifically to accommodate pressurized refrigerant, and because the molecules are smaller, they tend to leak faster out of sub-par hoses.
