Specifying Pneumatic Tubing Fittings is a Challenge to Many!

brass pneumatic fittings

The modern-days pneumatic systems are made in different varieties by manufacturing companies. People can easily access several choices to avail the air preparation systems, valves and cylinders connected. But brass pneumatic fittings experts don’t want to talk about all the pneumatic fittings. In this post, we will discuss pneumatic tubing and fittings.

Most designers apply flexible pneumatic tubing or hose instead of rigid tubing. Fittings provide several choices and meet the demands of a wide range of pneumatic system applications.

Pneumatic tubing and hose

Flexible tubing is the usual fitting used for connecting pneumatic valves to cylinders, actuators, and vacuum generators with hose a close second. Flexible tubing is different from rigid tubing and both are made of different materials.

Hose is crafted by adding a nylon braid between the inner and outer layers of tubing and attaching a swivel and rigid fitting. Regardless of the material used, a hose is strong, flexible and kink resistant. This is why it is the best way to connect shop air to blow guns or other pneumatic tools.

How you can select the right tubing material?

Since manufacturers are applying a range of materials to produce extruded pneumatic tubing, you can still make a choice as per your need.

Different materials used by the technicians are as under-

  • PVC
  • Polyurethane
  • Nylon
  • PTFE
  • Polyethylene

Polyurethane tubing is tough and has amazing kink resistance as compared to other material types. It has a working pressure of 150 psi or higher and is widely applied as tubing material. It also includes tight OD tolerance. Manufacturers offer a variety of tubing colors and diameters to help users determine pneumatic circuits.

Polyurethane and PVC tubing have superb flexibility. Polyurethane tubing is durable and you can select it for coiled, portable, or self-storing pneumatic hose applications. PVC is less tough than polyurethane, but you can consider it for food-grade applications.

Nylon and polyethylene tubing include harder plastic usage and thus, these both are comparatively less flexible than polyurethane. You can use nylon and polyethylene for air distribution and straight run piping applications.

PTFE tubing has high heat resistance, superb chemical resistance, and great dielectric properties.

You can always find these pneumatic fittings at the supplier outlet dealing in related hardware products. You can also ask for brass pneumatic fittings if you need some for your project.
