  • Patented IBVF Flanged Adaptors have been developed to address several common problems in the marine industry. Here’s what they do:
  • Eliminate dangerous thread miss-match when in-line valves are screwed onto thru hull
  • Accept standard thru-hulls into the base and standard in-line valves on top.
  • Provides a safe and sturdy assembly when in-line valves are used as seacocks.
  • For OEMs, prevent valve damage during engine or generator installation - the valve can be installed later.
  • Simplifies future valve replacement
