Patent pending IBVF flanged adaptors have been developed to addrss several age-old problems in the marine industry. Here's what they do:

• Eliminate common (and dangerous) thread mis-match when in-line valves are screwed onto thru hulls.
  
• Accept standard thru-hulls into the base and standard in-line valves or other components on top.
  

• Provide a safe and sturdy assembly when in-line valves are used as seacocks.
  
• Prevent valve damage during engine or generator installation - the valve can be installed later.
  
• Make future valve replacement a simple job.
  
• Available in Bronze and #316 SS models.
