A car air conditioning hose transports refrigerant in your vehicle's A/C system. The hose attaches to the A/C compressor while the low-pressure side is usually attached to the A/C fan.
The hoses must be perfectly tight as they work under very high pressure and temperature conditions in engine compartments, withstand vibrations, in contact with fluids and are exposed to constant stress from the vehicle's mechanical systems.
How to choose the right automobile air conditioner hose
The first step in choosing an automobile air conditioner hose is to choose the right size. This is important as the hose will be connected to many components of your vehicle. It should be long enough to reach all AC ports.
It's also important to choose a durable, low-pressure AC hose. Look for one made of a special material that resists corrosion and impact.
Another important thing to look for is a hose that's built to work with your specific refrigerant. The hose must be able to withstand the working pressure and the burst pressures of the refrigerant. You'll find these numbers on the hose itself and also on the metal fittings.
You should also check for Society of Automotive Engineers ratings. These ratings indicate that the product's tensile strength meets or exceeds the highest quality standards.
Once you have found the right low pressure hose, follow the manufacturer's instructions to replace the hose. This will prevent the hose's refrigerant from leaking. Having a leaky AC hose can cause you to lose cool air in your car and damage the rest of your system.
Fittings for automotive air conditioner hoses
Aside from the air conditioner itself, a properly fitted car air conditioning hose is the best way to cool down a sweltering summer afternoon. The best fittings are made of heavy duty steel, making them a safe and cost-effective choice for DIYers or professional mechanics alike. You'll find everything you need for your air conditioning system, from beadlock to compression line fittings.

production standards for automobile air conditioning hose
The hoses used in automobile air conditioning systems are usually made from high-quality rubber compounds. They have a very thin layer of nylon (polyamide) in the inner liner to reduce freon permeation down to the minimum.
In the case of a leak in the vehicle's air conditioning system, it is best to replace the hose as soon as possible. Failure to do this can result in refrigerant contamination or a malfunctioning expansion hose.
If your vehicle's temperature suddenly changes from cool to warm, it is likely that the expansion hose has failed and is not able to distribute the correct amount. You can immediately contact a mechanic if this happens.
Follow the manufacturer's instructions for proper installation and maintenance of your vehicle’s air conditioner system. This will help you to make sure that all of the connections are secured properly and correctly.
