Precautions to use a transparent PU duct hose
Characteristics of Compressed Air Hose
1. Length of air hose
Air hoses come in many sizes, usually 6 to 50 feet. The length of time you choose will depend on the type of work you intend to perform and the pressure required. You should note that the air pressure decreases as the length of the hose increases. If pressure is not an issue and you want to move freely while walking, you should choose a longer hose.
2. Inner diameter of air hose
The inner diameter of the air hose hose determines how much air it can carry and the type of valve that can be installed. However, your choice will largely depend on the CFM requirements of the air compressor (volume delivered at PSI level). Otherwise, you may leak frequently. The most common diameter size is 0.2 to 0.5 inches. When using a low CFM air system, 0.2 inches will be suitable, and the larger diameter is more compatible with high CFM equipment.
3. Air hose connector
Compressor hoses have different connection methods. There is a quick release connector, which is very suitable for switching between different pneumatic tools. The National Pipe Tapering (NPT) connection has a small hole size, which is ideal for low-pressure operation. Finally, there are threaded connectors, usually made of corrosion-resistant brass or aluminum. They are the best choice for automotive applications because they have wider holes in high-pressure applications and provide the best air-tight connection.
4. Air hose pressure rating
Before deciding to purchase, please read the pressure per square inch (PSI) provided by the equipment. This is the force by which air is expelled from the tube. Any device with a pressure of 150 psi can be used for heavy work, such as inflating car tires without breaking. Hose with a higher PSI rating has a longer service life and is ideal for extreme temperature conditions.
