Pneumatic & Hydraulic Fittings

Keeping your pneumatic and hydraulic assemblies moving is crucial to your operation. Make sure you’re moving forward with our range of hydraulic fittings and pneumatic connectors. Whether you’re searching for tube fittings, push connectors, or adaptors, we have a wide range of parts available in our collection online.

At Allied Electronics, we’ve developed a selection of high-quality, great-value pneumatic and hydraulic fittings and accessories that can help you connect the hoses, tubes, and pipes of a hydraulic system together. Whether they’re for home, commercial or industrial use, you’ll find everything you need and more right here.

What are hydraulic fittings and how do they work?

Hydraulic fittings connect hoses, pipes, and tubes in a hydraulic system. Most fittings and fixtures have a male and female component that join to form a connection. These help to contain and direct the flow of hydraulic fluid in a conductor, while preventing leaks and maintaining system pressure.

Depending on the hydraulic and pneumatic fittings you choose, you’ll be able to change the flow direction, elevation of lines, and split flow. When looking into methods of assembly, you’ll find that crimping is the most common. Once the crimp specifications have been checked for your hose and fitting, a crimping machine is adjusted to the appropriate diameter setting.

You’ll also notice that hydraulic connectors and fittings are made from a number of different materials including stainless steel, brass, and plastic. Because of the wide array of materials, they’re created from, pneumatic system fittings boast a range of performance capabilities.

It is more common for hydraulic fittings to be made from metals than plastic because higher pressures need stronger materials. Brass connectors are strong, durable, and corrosion-resistant. Stainless steel has a high heat resistance but is typically more expensive.

What are hydraulic fittings used for?

There are numerous applications for hydraulic fittings and pneumatic connectors. These parts are commonly used in hydraulic-powered applications in plumbing, robotics, assembly lines, and in heavy-duty equipment.

When looking at pipes and tubes for your application, it can be challenging to use them in moving operations because of their rigidity. For example, a construction digger that requires a hydraulic system but also needs the freedom of movement to operate their tool can place limitations on which hydraulic connectors are used. On the other hand, hydraulic pipes can allow flexibility in tool arm movements that are not possible with other tubes or pipes.

Another application that utilizes hydraulic fittings is in large complex vehicles like planes. They require hydraulics to operate wing movements and landing gears, using multiple hydraulics systems to help achieve movement.
