Everything You Need to Know About Hydraulic Fittings

Hydraulic fittings are used for connecting pipes and tubes in a hydraulic system. They typically operate under high pressure, so they must be versatile and strong to function effectively in their respective applications. Below are the major functions of hydraulic fittings.

What is the Purpose of Hydraulic Fittings?

Hydraulic fittings connect pipes, hoses, and tubes to various components such as valves, cylinders, or pumps. The fittings join to form a connection that prevents leaks, directs hydraulic fluid flow, and maintains a safe pressure level. The fittings come in different sizes and materials, like cast iron, steel, brass, aluminum, and polysulfone.

The common way of assembling fittings and hoses is by crimping. Once you check the crimp specification for a specific fitting or hose, a crimping machine adjusts it to the appropriate diameter setting. Afterward, the fitting is lubricated and put at the hose end next to a crimping machine.

There are various fittings used on the pipes, such as the elbow fitting, which is available in different sizes. It connects the ends of the pipe at a specified angle and thus can be used for various plumbing applications. Your plumber will advise you if you require fittings when completing the top three home projects: bathroom remodeling, installing new flooring, and interior painting.

While some companies use the no-skiving option on their hoses, others still use it. Skiving is the process of covering some part of the hose or removing the inner tube before attaching the hose end. The no-skive option is quicker and reduces the risks of hose damage. However, most hydraulic fittings are brand-specific, and thus they may not work with others.

What are the Common Connection Methods for Hydraulic Fittings?

Mechanical Seat Connectors

These connectors are common in most fluid power systems and have tapered seats. They offer a permanent connection, but they fit well with applications with occasional disconnections. These connectors do not require a sealing compound.

Interference Thread Connectors

These threads are among the first developed connectors and one of the most widely used. The pipe thread connectors have a tapered thread which makes a seal by deforming the threads, thus making it a permanent connection.

Soft Seal Connectors

The soft seal connectors use an O-ring connector to prevent leaks. The connectors resist vibrations, have a high-pressure capability, are easy to assemble, and can be used in various applications. The major O-ring connectors are flange-face seal, flat-face O-ring, and boss O-ring.
