The IBVF Flanged Adapters are very handy and have been developed to address several common problems in the marine industry.  


  • Eliminates the dangerous thread miss-match when in-line ball valves are screwed onto thru hulls which is not allowed under ABYC standards.
  • Accept standard thru-hulls into the base and standard in-line valves on top
  • Provide a safe and sturdy assembly when in-line valves are used as seacocks and meets ABYC strength standards
  • For OEMs, prevent valve damage during engine or generator installation - the valve can be installed later
  • Simplifies future valve replacement
  • Made from C83600 Bronze also know as 85-5-5-5 bronze
