Model 810 Pneumatic / Hydraulic FRU
FLUID ROTARY UNION (FRU)
The Model 810 Fluid Rotary Union (FRU) is designed for industrial and marine applications where multiple fluid passes need to be transferred across a rotational interface. There are various standard designs, depending on the application.
The standard Model 810 FRU is available with two or four threaded passages of size 1/2 or 3/4 inch. A 1/2 inch on-axis wire pass for integration with an electrical slip ring, fiber optic rotary joint or both.
The Model 810 utilizes sealed-for-life rolling element bearings to provide long trouble free service. Filled PTFE based seals run on a hardened surface to provide long service life, minimizing frictional heat generation and operational torque.
For marine applications, the Model 810 is available in hybrid and fully stainless steel versions for added corrosion protection. More variations of port size and channel count available. Please contact factory for further details.
