IBVF Series Flange Adaptor (2” NPT)

Thread bottom NPS: 2". Thread top NPT: 2". Eliminate dangerous thread mismatch when in-line valves (tapered NPT threads) are screwed onto thru-hulls (straight NPS threads). Accepts standard thru-hulls into the base and standard in-line valves on top. By spreading the load across a greater area, IBVF provides a safer installation 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. C83600 bronze construction.
