Cast Bronze Fitting Reducer

• Description：Cast Bronze Fitting Reducer,Bronze Fittings/Marine Boat Reducer Coupling Bronze/Brass Threaded Reducer Coupling,Lead Free & No lead Bronze with thread connection type.
  The bronze reducer use sand mould to shape,and CNC machines to thread.The surface is sand blasted.Runde supply wide range bronze fittings.All the fittings can process BSPT NPT, NPSM, BSP thread.And we can cast the material according to the customized metal grad.
  Runde bronze fittings' quality is same as yorkshire bronze fittings ,pegler bronze fittings,connex bronze fittings,kembla bronze fittings.The cast bronze fitting reducer know as gunmetal fittings has flange at the edges,The thread meet ISO228 and 7-1 as well as ASME B1.20.1.
