Applications
Deublin rotary unions are precision fluid-transfer couplings used in rotating machinery to pass liquids or gases — such as coolant, hydraulic fluid, water, air, or steam — through a rotating shaft or spindle without leaking. They are standard components in machine tools (CNC lathes, milling machines, grinding machines), paper and converting equipment, plastics processing, printing presses, and other industrial machinery where a stationary fluid supply line must connect to a rotating element. This rebuild kit is used to service and restore Deublin 3/4 inch BSP right-hand rotary unions when seal wear or internal component fatigue causes leakage or reduced performance, extending the service life of the rotary union rather than replacing the entire assembly. Deublin has been a leading manufacturer of industrial rotary unions since the 1940s, and genuine OEM rebuild kits like this ensure correct fit and seal material compatibility.
This Deublin 255-000B284 Rebuild Kit for 3/4 inch BSP RH rotary unions is new and unused in its original Deublin box. The photos show all kit components — the stainless rotary union cartridge (in original plastic wrap), coil spring, snap ring, and red protective seal cap — complete and in new condition. The box shows minor shelf wear typical of new old stock storage, but the contents are undamaged and unused. Please view our photo set and contact us if you have any questions.
