You will also learn its various types and sizes. Then we will tell you about global air hose standards & how you can easily measure the exact size of air hoses.
What is an Air Hose?
An air hose is a flexible tube that is used to carry pressurized air from a compressor to a machine or other location. Basically, its one end connects to an air compressor or air source, and the other side attaches to pneumatic tools. It is widely used in construction, automotive maintenance, and industry. You can also call it an air compressor hose.
Air Hose Material: It is designed to withstand the pressure of compressed air so that it does not crack under heavy load. This is due to the reason that air hoses have such material which provides them strength to handle it. Main materials that are used in air hose manufacturing are:
- Rubber
- Polyvinyl chloride (PVC)
- Polyurethane
- Hybrid blends
- Nylon
- Silicone
How Does an Air Hose Work?
Air hose is a sealed conduit that acts as a path between a compressor and equipment. It does not create pressurized air by itself. You can only use it to transfer compressed air at your desired location. To measure air pressure inside the hose, you can use a PSI (pounds per square inch) unit. The air hose has a reinforced layer that handles this pressure easily.
However, the SCFM (standard cubic feet per minute) unit tells you how much compressed air is flowing from your hose in one minute. With the help of this measurement, you can make sure that your tools get the required pressure or not. The couplers, plugs and fittings are used to create a tight seal of air hose on both sides. So that there is no chance of leakage.

- Pneumatic Tools: In auto repair shops, it is used to power impact wrenches, nail guns, ratchets and sanders. You can utilize air hoses at construction sites in heavy tools such as jackhammers and concrete breakers.
- Inflation: You can install air hoses with tire inflators at your gas stations. With the help of it, you can fill cars, bicycles and trucks tires easily. It helps you to transfer compressed air in vehicle tires.
- To Clean Things: If you want to clean your work surfaces and machineries, you can use an air hose with blow guns. It delivers pressurized air which helps you to remove the debris, dust and wood shavings.
- Industrial Automation: Air hoses helpful to operate pneumatic cylinders, clamps, actuators, valves and robotics. It also provides compressed air to production equipment and automated machinery.
- Workshops and Transportation: In large commercial trucks and railway trains, air hose is used in the braking system to supply pressurized air. At your workshop, you can attach compressors to air-powered tools by air hose.
Can you use air hose for water? If you want to carry a small amount of water and have no other option, you can use it temporarily. But it should be compatible with water. You should avoid using air hoses for long-term and high-volume water.
Air Hose Sizes Chart
You can measure the size of an air hose by its inside diameter (ID). It helps you to determine how much airflow the hose can supply to your pneumatic tools easily.
Does length of air hose affect pressure? Yes, the length of your air hose can cause a decrease in pressure. As compressed air passes through the hose, it rubs with the inner walls. As a result, pressure drops at your tool. If you use a long hose, the pressure decreases with its length.
| Hose Size (ID) | Working Pressure (PSI) | Airflow (CFM/SCFM) | Recommended use/tools |
| 1/4 inch (6.35 mm) | Up to 150 psi | 1 – 4 CFM | Airbrushes, nail gun, tire inflator |
| 3/8 inch (9.52 mm) | 150 – 300 psi | 5 to 10 CFM | Impact wrenches, spray gun & nail guns |
| 1/2 inch (12.7 mm) | Up to 300 psi | 10 – 30 CFM | Heavy-duty tools such as sanders, grinders |
| 3/4 inch (19.05 mm) | 100 – 300 psi | 30+ CFM | Industrial pneumatic tools and jackhammers |
What Size Air Hose Do I Need?
If you want to use an air hose for your light-duty tools such as brad nailers, you can choose 1/4-inch ID hose. While you can use a 3/8-inch ID hose for your workshop applications. It is also ideal for heavy equipment like impact wrenches. To get higher pressure, you need to use a shorter hose. Because it causes less friction to the airflow.
How to measure air hose size?
To replace your old air hose, you have to check its size marking, which is usually printed on its outer surface. If you do not find it, you have to measure the air hose size yourself. For this process, you can adopt the following steps.
- You have to look at the cut or open end of the hose and measure its inside diameter (ID) with a digital caliper.
- You must place the jaws of the caliper across the inside of the hose. It shows you the exact diameter of the air hose.
- If you do not have a caliper, you can use the shank side of drill bits. You have to determine which size fits properly inside the hose.
- Then, compare your millimeter or inch reading to common industry standards such as 1/4, 3/8, 1/2, and 3/4 inch.
- To determine the fitting size, you can use a thread pitch gauge and a ruler. You should avoid mixing the hose’s fitting size and inside diameter.
