Swivel Union-GZ Hydraulic Fittings
Swivel Union-GZ hydraulic fittings are components used in hydraulic systems to connect and seal hydraulic hoses, tubes, and pipes. These fittings provide a secure and leak-free connection between different hydraulic components, allowing the transmission of hydraulic fluid under high pressure.The "Swivel Union" refers to the ability of the hydraulic fitting to rotate or swivel, providing flexibility and ease of installation. This feature allows for angular movement between connected components without causing stress or strain on the hose or pipe. Swivel Union-GZ hydraulic fittings are particularly useful in applications where there is a need for movement or rotation, such as in heavy machinery, construction equipment, and hydraulic systems with moving parts.Swivel Union-GZ hydraulic fittings are typically made from high-quality materials such as stainless steel, brass, or carbon steel, depending on the specific application and compatibility requirements. It is important to select the appropriate fitting based on factors such as pressure rating, temperature range, fluid compatibility, and the specific needs of the hydraulic system.
