Deublin 257-000-285 LH Rotary Union is a rotating fluid-transfer connector that creates a sealed interface between a stationary supply and a rotating component, enabling continuous fluid delivery without hose twisting. It uses 3/4" BSP threaded ports for inlet and outlet connections, aligning with standard British Standard Pipe sizing. Designed with a left-hand orientation, this rotary union supports reliable operation in equipment where a rotating part must receive a feed line while the stationary system remains fixed. The part number 257-000-285 uniquely identifies this Deublin model for replacement and compatibility in systems that specify a left-hand, 3/4" BSP rotating union.
