Groco #316 Stainless Steel NPS to NPT Flange Adaptor

The Concept: 

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 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.
