The complete manufacturing process of our custom rotary unions takes place in our facility in Laurens, IA. Each unit is 100% pressure tested during rotation to assure performance prior to shipment.
Built, assembled, and tested in Laurens, Iowa.
All custom rotary union manufacturing processes are performed in the Positech facilities: machining, grinding, honing, assembly, and testing. The rotary union cases are made of steel, and are bored, drilled, welded, stress relieved, honed, milled, and deburred before oil seals are cut into the spool. Almost any kind of port can be put into the spool or case. Chrome plating of the rotary union case ID is available.
