Externally calibrated pneumatic tubes are primarily used as compressed air and hydraulic lines. They represent today's standard in pneumatics and fit all common screw connections (e.g. QS, NPCK). The outside diameter of the tube is specified as the tube size.
The requirements regarding pressure, temperature, flexibility and environmental influences differ from industry to industry. Around 90% of all cases of damage can be traced back to the incorrect selection of tubes and their materials. The consequences are energy losses and machine downtimes as well as flow losses. It is all the more important to find the right pneumatic tube for your application among the numerous products.
We carry a wide range of externally calibrated pneumatic tubes. A popular product from our core range is the plastic tube PUN-H, which has proven itself to be used with QS screw fittings. It is made of polyurethane and is available in 14 different colors and as a single tube or double tube version. It has excellent kink resistance and can be used flexibly, even in the food industry due to the high-quality material. PUN-H is particularly resistant to microbes and hydrolysis and is therefore ideal for laying cables quickly and reliably.
Of course, you will also find other pneumatic tubes with external calibration at Festo, tailored to your requirements. From tubes made of polyamide, polyurethane or polyethylene to customer-specific tubes with an individual design and tubes in your desired length – all our pneumatic tubes are economically attractive and safe for your application.
At Festo you will find suitable accessories for externally calibrated pneumatic tubes, e.g. to prevent the tube from kinking/pinching off. In addition to tubing straps, spiral wraps for tubing and two types of tubing support, we can supply you a multi-tube holder to professionally store extensive tubing systems. Additional accessories for externally calibrated pneumatic tubes are our pipe and tubing cutters and connecting pliers for attaching and removing the plastic tube to/from the barbed fitting.
