Modern Pu Air Hose comes in a wide variety of synthetic materials, which have largely replaced the older styles of rubber hose. Lightweight materials can be reinforced with braided steel wire or fibre layers. These give the hoses great strength and resistance, while allowing them to remain very flexible. Deciding how to choose the right air hose material will depend on its function and place of use, particularly if your application is to be in a hazardous or extreme environment.
Polyurethane is a thermoplastic material similar to PVC, which is often considered a good general-purpose hose material. It's a lightweight, abrasion-resistant option, with a surprisingly long life, and remains flexible in a wide range of working temperatures. It's more flexible than PVC and lighter than rubber, but is prone to kinking. This material is a good choice for more mobile applications.
Nylon hose is generally lightweight and easy to store, while being resistant to abrasion and good for high-pressure applications. Nylon hosing has low permeability coupled with excellent dimensional stability, but it kinks easily and doesn't last as long as more durable options.
Neoprene is a very lightweight form of synthetic rubber, which makes for a highly flexible hose. It's capable of great precision in the work area, in pressures up to 200 psi, and can resist both heat and cold.
EPDM is another form of synthetic rubber hose used in industrial, agricultural and construction applications. EPDM offers a high resistance to both heat and cold, and great flexibility even at low temperatures. Hoses made of this material are weather and ozone-resistant, so they're good for outdoor applications, as well as being mildly resistant to chemicals.
Thermoplastic hoses are generally constructed of various polymers such as polyurethane or PVC, and bonded and reinforced with a layer of braided steel or fibres. They're extremely resistant to extremes of climate or environment, and have a low expansion rate. The strength of bonded thermoplastic hoses makes them popular for use in rigorous industrial applications.
For safety reasons, you must choose a hose with a maximum working pressure that's greater than that of your pneumatic application. This means you should check the pressure at which your application operates, correlate it with the correct l/min, and select your hose based on the highest potential pressure of the piping system. We recommend you double-check the specifications of all parts of the system before choosing a specific hose.
