GROCO 3/4" #316 Stainless Steel NPS to NPT Flange Adapter [IBVF-750-S]

Patent pending IBVF flanged adaptors have been developed to address 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.
