Groco IBV-F Bronze Flanged Adaptor (Not for Portable Water Systems)

Adapter eliminates dangerous thread miss-matches between thru-hulls and in-line valves and valve damage in OEM installations. Accepts a standard thru-hull fitting into the base and a standard in-line valve (or other tapered thread component) on top. Also provides a safe, sturdy assembly when in-line valves are used as seacocks.

NOT TO BE USED IN POTABLE WATER SYSTEMS.
