When choosing your pneumatic fittings, there are some key environmental factors that must also be taken into account. Why is machine safety so important? Hose is designated by its internal diameter, and usually comes with rigid, swivel or quick-disconnect fittings that are attached at both ends. These fittings can be used in many varied roles, depending on the specific type of function performed.
Always use straight runs wherever possible, and only use elbows and Ts if absolutely necessary. 0000005461 00000 n Shaped fittings ensure the effective design of a pneumatic system, with various unions and adaptors to reduce or increase the pipe diameter, or provide a neat continuity across fittings. In order to break down this process, you first need to identify: The design of pneumatic fittings should allow the free flow of required air or gas without any opportunity for significant drops in pressure.

Tubing in pneumatic systems is often something of a halfway house between hose and pipe; a relatively rigid option but with some degree of flexibility and aimed at less permanent setups than most conduit pipe assemblies. When deciding how to choose your pneumatic fittings, you need also to determine what type and size of tubing or hose you will need, whether it is measured in metric or imperial sizes, and whether it's made of metal or thermoplastic. It is often designed to be replaced at fairly regular intervals due to general wear and tear. Pipes are entirely rigid, constructed from a single solid material and usually defined by their internal diameter dimension.

Hose is generally more expensive than tubing but is more rugged and durable, as it is often used for manual tools and gets dragged across abrasive surfaces. Push-in Fittings allow the tube to be secured by pushing it through a collet or grab ring and can be released simply by pushing a release collar. Some common examples include: These fittings are characterised by an angled joint, commonly 90 degrees (right-angle). If the correct operating pressure is not maintained, it could cause the whole system to fail, and components are likely to leak, break or lose their pressurised seal.

Fittings sold with straight threading are intended to form a solid connection between parts, but not necessarily to form an air-tight seal on their own - this threading type will require additional sealant coating or a layer of Teflon tape for use in pneumatic applications.
A hose is typically understood to refer to a flexible type of conduit, constructed from multiple layers of robust rubberised or plastic material. Tubes are relatively rigid vessels generally made from one solid material, typically some kind of thermoplastic, which can also be internally reinforced for higher strength: Hoses are completely flexible vessels constructed from a variety of the same thermoplastic materials. The most common air contaminants are water, oil and particulates, such as dirt, rust and metal shavings.

Thread size is always measured and formulated on the interior diameter of the conduit and corresponds to a specific number of threads per inch (TPI). 0000181582 00000 n
A pipe in this context usually denotes a conduit constructed from more solid materials, often in a single layer or length, and generally seen as a better option for more permanent installations or runs. It can safely be used for applications in exposed areas, because it is resistant to weathering, ozone and UV radiation.
Always use straight runs wherever possible, and only use elbows and Ts if absolutely necessary. 0000005461 00000 n Shaped fittings ensure the effective design of a pneumatic system, with various unions and adaptors to reduce or increase the pipe diameter, or provide a neat continuity across fittings. In order to break down this process, you first need to identify: The design of pneumatic fittings should allow the free flow of required air or gas without any opportunity for significant drops in pressure.

Hose is generally more expensive than tubing but is more rugged and durable, as it is often used for manual tools and gets dragged across abrasive surfaces. Push-in Fittings allow the tube to be secured by pushing it through a collet or grab ring and can be released simply by pushing a release collar. Some common examples include: These fittings are characterised by an angled joint, commonly 90 degrees (right-angle). If the correct operating pressure is not maintained, it could cause the whole system to fail, and components are likely to leak, break or lose their pressurised seal.

Aluminium fittings are commonly used for low pressure, low density applications where its low tensile strength is not an issue. 0000003030 00000 n
Fittings sold with straight threading are intended to form a solid connection between parts, but not necessarily to form an air-tight seal on their own - this threading type will require additional sealant coating or a layer of Teflon tape for use in pneumatic applications.
A hose is typically understood to refer to a flexible type of conduit, constructed from multiple layers of robust rubberised or plastic material. Tubes are relatively rigid vessels generally made from one solid material, typically some kind of thermoplastic, which can also be internally reinforced for higher strength: Hoses are completely flexible vessels constructed from a variety of the same thermoplastic materials. The most common air contaminants are water, oil and particulates, such as dirt, rust and metal shavings.

Some of the most common include: This type is designed with speed and ease of assembly/disassembly in mind, but they are also built to provide a secure and reliable join. Thread size is always measured and formulated on the interior diameter of the conduit and corresponds to a specific number of threads per inch (TPI). 0000181582 00000 n
A pipe in this context usually denotes a conduit constructed from more solid materials, often in a single layer or length, and generally seen as a better option for more permanent installations or runs. It can safely be used for applications in exposed areas, because it is resistant to weathering, ozone and UV radiation.
