Hydraulic fittings, including adapters, caps, and couplings, are crucial for connecting and sealing hydraulic lines in machinery and equipment. These fittings ensure the safe and efficient transfer of hydraulic fluids, which is essential in applications such as construction, agriculture, and manufacturing. Designed to withstand high pressures and harsh environments, hydraulic fittings provide reliable connections that prevent leaks and ensure smooth operation of hydraulic systems, enhancing equipment performance and longevity.
