Groco Bronze Flanged Adapter for In-Line Ball Valve to Thru-Hull

The Groco Bronze Flanged Adapter (IBVF series) is a bronze flange adaptor, also called a flanged adaptor, that connects an in-line ball valve to a thru-hull fitting. It removes the thread mismatch that can happen when tapered-thread in-line valves are screwed directly onto straight-thread thru-hulls. It gives you a sturdy, secure connection for seacock and plumbing setups on boats.

Key Features:

• Prevents dangerous thread mismatch between thru-hull fittings and in-line valves
• Takes a standard thru-hull fitting in the base and a standard in-line valve or other tapered-thread component on top
• Makes a safe, sturdy assembly when in-line valves are used as seacocks
• Helps OEMs avoid valve damage during engine or generator installation, because the valve can be installed later
• Simplifies future valve replacement
• Cast from C83600 bronze
• Patented flanged design
• Meets the ABYC H-27 standard

Groco is a trusted name in marine plumbing and seacock hardware. These adapters suit boat owners, builders and installers who want a more reliable thru-hull and valve connection. Not for use in potable water systems.
