Order your pneumatic tube from our wide range. Pneumatic hoses are used to connect air-driven devices such as valves, grippers and cylinders. If you want to operate a pneumatic cylinder with a solenoid valve, you usually use a pneumatic hose. For systems that do not work on compressed air, but for example on oil (hydraulics), hoses are available that have properties that are more effective in such systems.
Polyurethane (PU) is very flexible, kink resistant and durable. These properties are retained even at high and low temperatures. For these reasons PU is the most commonly used material for pneumatic controllers, robotics and vacuum systems. Note that some polyurethane-based tubing/hoses have reduced resistance to water or humid environments. PU based on ether is resistant to water and fungus growth. Alternative materials are polyethylene (PE) or polyamide (PA or nylon). PE is used for low pressure pneumatics. It is resistant to many acids, bases and salt solutions. It is less flexible than PU, but more flexible than PA. The material costs of PE are somewhat lower than PU. PA is strong and light, but less flexible than PE and PU. On the other hand, it has excellent chemical resistance, is resistant to UV radiation, can be used for higher working pressures and is also used for hydraulic oil or fuels in addition to compressed air.
Pneumatic hoses come in many shapes and sizes. You almost always need a fitting to connect the hose to a device. Common fittings for PU hoses are plug-in fittings. However, these are not suitable for reinforced hoses, soft rubber or silicone hoses or rigid PE or PA plastic tubes. For PE or PA hoses often hose pillars or compression fittings are used.
