The wires of the pneumatic world are tubing and hoses. Here’s how to choose between the two, and how to apply each in industrial plants and facilities. The world of fluid power may not be full of new and amazing products, but it’s used daily and requires connections via tubing and hose. Starting at the air compressor, fluid power is distributed through pipes to plant or area filters and dryers, and then on to machine air preparation systems. Once compressed air lands at the machine, tubing and hoses make connections to valves and cylinders. Tubing, hose and related fittings—often sold in bulk—are the final pieces to plumb and connect pneumatic devices. This article looks at some differences between tubing and hose, and discusses related fittings. Best practices for design, selection and implementation are also covered. Tubing and hose Modern pneumatic systems for industrial automated machines typically don’t use rigid connections, but instead use flexible tubing or hose, available in many different types. Tubing is specified by outside diameter—for compatibility with push-to-connect fittings. Hose is specified by its inner diameter, and is typically sold with swivel, rigid, or quick-disconnect fittings attached at both ends.
