Pressure fittings, also known as connectors or adapters, are connections that join pipes, manifolds, tubes, valves, hoses, and other components – and most systems have a lot of them.

In order to achieve dependable operation, each fitting must be able to manage the system media and pressure without leaking. Although most fluid system specialists only need to be familiar with one or two types of fittings for their jobs, some sectors require a wide range of knowledge.

It’s all about matching the materials to the job and the environment when it comes to pneumatic polyethylene pipe fittings. To break down this procedure, you must first determine:

Work Environment

Pneumatic fittings should be designed to allow for the free flow of required air or gas with no major pressure drops. Pipes and hoses should be as simple as possible to ensure that no energy is lost during the flow of air through the system. When feasible, stick to straight runs and only use elbows and Ts when absolutely required.

Air Pressure  

Pneumatic fittings are commonly rated for certain working pressure ranges based on the equipment’s specifications and intended use. This is the pressure range (in PSI) where a pneumatic system will work at its best. If the proper working pressure is not maintained, the entire system may fail including poly fittings supplies with components leaking, breaking, or losing their pressurised seal.

Fitting Material

When determining how to choose the right pneumatic fittings for your application, you should look at the various materials that are typically used to establish their physical properties, gas compatibility, and reaction to temperature changes, for example. Common fitting material include:

  • Brass

Brass is also corrosion resistant, but it is significantly stronger and more durable, with good conductivity and ductility at high temperatures. Because of its good performance and machinability, it is frequently used for pneumatic fittings.

  • Aluminium

Aluminium fittings are frequently utilised in low-pressure, low-density situations where tensile strength isn’t a concern. It is a lightweight material that is frequently chosen for its corrosion resistance, but it can also be alloyed with other metals to boost its strength and density.

  • Plastic

Polypropylene is a thermoplastic frequently used for pneumatic fittings because of its great durability, low cost, and broad compatibility with various materials. Polyethylene pipe fittings have outstanding biaxial strength, cold flow, and yield elongation characteristics. Because it is resistant to weathering, ozone, and UV radiation, it can be utilised safely in exposed regions.

Tube Type

When choosing pneumatic fittings and poly fittings supplies, consider the type and size of tubing or hose you’ll need, as well as whether it’ll be measured in metric or imperial sizes and whether it’ll be composed of metal or thermoplastic. And, first and foremost, you must distinguish between tube, pipe, and hose. For more information visit our website:
