Pneumatic hoses and tubing are used to transmit pressurized air to valves, actuators, and other component s of the pneumatic system. These assemblies are flexible, which makes them an excellent replacement for rigid connections. In fact, pneumatic systems rarely make use of the latter, especially the ones used in industrial automated machines.
Hose and tubing assemblies come in various types. Before we proceed to unpack the two different accessories and how they complement a pneumatic system, we must first know what distinguishes them from one another.
A hose is specified by the inner diameter, while the outer diameter is used for tubing specifications. In addition to this, hoses are typically available with fittings attached at either or both ends, although tubing also makes use of these add-ons.
What Are Hose and Tubing Assemblies Made Of?
Several materials may be used to manufacture hoses and tubing. These include polyurethane, polyvinyl chloride (PVC), nylon, polyethylene, and polypropylene. While each of these has their own set of advantages, nylon tubing assemblies particularly stand out.
Nylon isn’t as flexible as polyurethane and PVC. Being a harder plastic, it may be slightly more rigid in contrast with the other materials. However, nylon is still flexible enough to be used for tubing and hose assemblies. It’s especially useful for straight-run piping and air distribution used at plants.
In addition to this, nylon also works tremendously well in high heat and high-pressure environments. Its ability to withstand high pressure combined with its resistance to corrosive chemicals and flexural fatigue makes it an even more useful material for tubing and hoses.
Nylon also is lightweight, dimensionally stable, and has low water absorption. These properties make it a great fit for tubing and hose assemblies.
What Type of Fittings Do They Require?
The most popular choice of air fittings for these hose and tubing assemblies are push to connect fittings. They help connect the flexible (nylon) tubing with the rest of the components of the pneumatic system and industrial machinery, including other tubing.
Push to connect fittings are mostly made of a thermoplastic, stainless steel, or brass body. They may also be nickel-plated. The push to connect tube fittings come in various shapes and designs, such as straight fittings or elbow fittings, and help hold the tubing and hose assemblies together while connecting them with other components.
