Groco IBVF Series Flanged Adapter

Groco IBVF Series Flanged Adapters (Patent Pending) were developed to eliminate the common and dangerous problem of thread mismatch when NPT Inline valves are screwed directly to NPS-threaded thru-hulls.

Features:

• Provides a safe and sturdy assembly when in-line valves are used as seacocks
• Eliminates thread mismatch when in-line valves are screwed onto thru-hulls
• Accepts standard NPS thru-hulls into the base and standard NPT in-line valves or other components on top
• Prevents valve damage during engine or generator installation – the valve can be installed later
• Makes future valve replacement a simple job (can even be done in the water when plugged from the outside)
