In hydraulic and pneumatic systems, fittings provide the connections between hoses, pipes, and other parts of the installation, including valves, pumps, and tanks. The large availability of Couplings and other fittings can be somewhat confusing and create misunderstanding on their peculiar characteristics. In general, a fitting is a part designed to provide a reliable connection with other components. An adapter is a component that forms a joint between couplings having different types or sizes. In some cases, adapters can work as fittings. The creative but rigorous combinations of different fittings allow designers and engineers to compose efficient hydraulic systems, getting the most from each installation.
Adapters are made from various materials including rubber, brass, and steel. Available types cover all the possible situations; the frequently used ones are female to female, male to female, male to male, barbed, and female cap nut variants, among many others. You can find a wide range of hydraulic pipe thread adapters on our virtual shelves. Made by trustworthy companies, our products meet the highest industry standards for the category and are offered at reasonable prices.
