Pneumatic hoses and fittings

Pneumatic hoses and fittings: what you need to know

Pneumatic hoses are used to convey compressed air from a compressor to a tool. Fittings are parts that connect elements of pneumatic hoses. If necessary, they can be used to make branches in the air supply system.

What are the types of pneumatic hoses?

By material:

• Rubber hoses are inexpensive and rather heavy.
• Polyethylene ones are characterised by a high resistance to the impact of aggressive chemicals.
• Polyurethane hoses are lightweight, characterised by increased durability and withstand low temperatures.
• Polyamide hoses do not deform at extremely high temperatures (up to 110 ºC) and do not crack, when it is freezing (up to −60ºC).
• Vinyl hoses are tangle-resistant, feature flexibility and long service life.

By shape:

• Coiled. They do not tend to twist when being used, convenient to store and easy to fold.
• Straight hoses feature a robust design. They need much space. It is necessary to be sure that the hose isn’t twisted while using it.

What are the types of fittings?

By connection type:

• Standard. They ensure a durable and reliable connection. They require special tools to install and remove them.
• Push-to-pull. They are equipped with a special mechanism which ensures a quick coupling. They are very useful if there is a need to attach different tools to the same air compressor.

Made of the following materials:

• polyurethane;
• polyamide;
• copper;
• nickel-plated steel;
• stainless alloys.

By connection method:

• Threaded. Designed for hoses with connectors.
• Flare. Used with accessories without connectors.

Tips on using air hoses and fittings

Check whether the diameters of the parts are compatible. If these elements are not securely fixed, using pneumatic equipment is dangerous. Make sure that the flow efficiency of the parts complies with the specifications of the air compressor. Otherwise, the system won’t function properly.

While working you should always be sure that the hose isn’t twisted. Bends might cause cracking.

Check the fitting not less than once in three months to make sure that the connections are tightened and sealed.

Pay your attention to the purity of compressed air. Dirt and moisture are bad not only for air tools but for pneumatic hoses as well.
