Couplings are the essential parts of any hydraulic system. They are used to connect hoses and pipes to the other elements of the system including reservoirs, cylinders, valves, and pumps. Designed according to strict requirements, couplings are available in many types and materials compatible with the fluid circulating in the system. It is vital, hence, to pick the most appropriate class of fittings to get smooth running, top performance, and safety. Common materials include brass, stainless steel, aluminum, plastic, and copper. For example, plastic couplings offer good resistance to corrosion, but they are unreliable in high-pressure systems.
The choice of hydraulic couplings depends on the pressure rating, chemical compatibility with the fluid, operating temperature, and sealing capacity. Crimp fittings, coupling barbs, compression fittings, and quick disconnect couplers are the most common types used in hydraulic systems. Typically, they are available in many sizes and shapes to fit various designs. In our online catalog, you can find a wide assortment of these and other couplings including inverted flares, mini-barbed tubes, and reusable models. We also offer a broad selection of adapters to ensure flexibility and efficiency. The costs are reasonable, and the quality is ensured by leading companies in the industry.
