    1-1/2" #316 Stainless Steel NPS to NPT Flange Adapter

    IBVF Flanged Adapters have been developed to address several common problems in the marine industry.  


    • Eliminate dangerous thread miss-match when in-line valves are screwed onto thru hulls
    • 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
    • For OEMs, prevent valve damage during engine or generator installation - the valve can be installed later
    • Simplifies future valve replacement
