A wide range of pneumatic tubes for many applications

Cole & Swallow Metals specialise in tubes for use in the manufacture of pneumatic cylinders. Produced and manufactured from quality aluminium alloys in Switzerland to internationally recognised standards for the pneumatics industry.

We are able to offer from our stock, the complete range of standard sizes and with our manufacturers in Switzerland, can also meet your requirements for bespoke sizes. For more information about how Swallow can meet your requirements or meet unusual product specifications, please contact us.

Pneumatic tubes perform essential functions in many industries and applications, often using off-the-shelf products. Some uses however need bespoke shapes, tolerances, finishes or properties, specially tailored to the application. Whether off-the-shelf or bespoke, Swallow Metals can supply the right solution for your needs.

Many of our customers prefer to order their pneumatic tubes complete and ready to install, rather than in component or semi-finished condition.

Swallow can deliver your order manufactured to whatever level of completion that is required.

Our supplier only uses manufacturing equipment that is up-to-date, ensuring cost efficient production and delivering consistent quality, further guaranteed by our rigid adherence to our ISO9000 quality system.
