Pneumatics of any kind is not something most people think of when talking about machines or equipment of any kind. Such as electric or diesel motors, maybe even robots etc. But the fact is that pneumatics is present in almost every industrial application and in our daily lives. A lot of equipment, from coffee makers to the brakes on a bus, can be powered by pneumatics. In all instances, gas or air is compressed and then released in a controlled way to harness its power. That is what pneumatics is in a nutshell. And where ever there are pneumatics, there are also pneumatic fittings.
Where are they Used?
Pneumatic fittings are used in a wide range of products. The following are some examples.
- Pressure gauges
- Nail guns and spray paint equipment
- Pneumatic doors
- Shock absorbers
- Door stoppers
- Brakes on large vehicles
There are several types of pneumatic fittings available today, and each type is designed according to what type of function it will be doing and where it is going to be connected. Some are connected to pipes and others will be attached to hoses. They can also be made from a wide variety of materials. the following are some of the more common types.
The pneumatic push on fitting is one of the more tougher types of fittings available. It takes a little longer to attach it but on the other hand, they are more reliable to use. They grasp the hose well due to the presence of a nut that can be tightened. This fitting also comes with a swivel end which means pipes and hoses do not need to be twisted to fit it on. This makes the fitting process steadier as well as more reliable. Push on fittings are also some of the best for higher temperature environments.
Brass and Stainless Steel
If you need a pneumatic fitting that will remove and attached often, then brass fittings are an excellent choice. Most brass fittings will be coated with nickel which gives it some added protection. Brass is also the choice for pipes made of plastic, rubber or polyurethane. Another reason for their popularity is the price. Compared to other metal based fittings brass is a little cheaper.
Stainless steel fittings are some of the most durable. Not only can they handle corrosive environments but high heat also. They are also capable of handling very high levels of air pressure. The reliability of stainless steel makes it a popular in applications where reliability trumps everything else. Because of these reasons stainless steel fittings are some of the more costly ones.
One of the most common pneumatic fittings is the plastic fitting. The reason for this is because a lot of applications do not call for fittings capable of withstanding high heat and pressure. Plastic is not capable of these extremes. However, they are usually considerably cheaper compared to other types. They area also lighter and easier to fit onto hoses and pipes. They are also pretty good at handling corrosive environments, although not as good as stainless steel fittings.
