To connect pipes, hoses, and tubes in a hydraulic system, fittings are necessary. Typically, fittings are designed and manufactured according to strict standards that determine appropriate design, size, and pressure ratings.
Fittings are also made of different materials, including metals and plastics, depending on the requirements of the application. For example, the high pressures of hydraulic systems require the use of stronger, more durable material.
Hydraulic fittings are available in a variety of forms, such as flare fittings, threaded pipe fittings, and flanges. Each type of hydraulic fitting has its own unique design and function.
Flare fittings are used to connect tube lengths and allow for expansion. They are also suited for wide temperature variations and are less expensive than other types of fittings.
Threaded pipe fittings are made from a variety of materials, including aluminum and stainless steel. These are popular choices because they are lightweight and are easy to machine. However, they are prone to leaks.
Stainless steel - stainless steel is resistant to corrosion and has good abrasion resistance. It is often alloyed with zinc, copper, and other materials for added strength.
Plastic - polypropylene is the most common material used in hydraulic fittings. It has excellent cold flow, bi-axial strength, and yield elongation properties.
The hydraulic components that work under high pressure need to be durable, versatile, and reliable. The right hydraulic accessory can make the difference between a malfunctioning system and one that is safe and effective.
