Groco IBVF1500 1-1/2" Bronze NPT to NPS Flanged Adaptor

The Groco IBVF1500 is a 1-1/2" bronze flanged adaptor that eliminates dangerous thread mis-match when NPT in-line valves are screwed onto NPS thru-hulls and meets ABYC H-27 standards. Constructed from durable C83600 bronze, this patented adaptor addresses critical safety concerns in marine plumbing installations.

Key Features:

• Eliminates dangerous thread mismatch between in-line valves with tapered NPT threads and thru-hulls with straight NPS threads
• Accepts standard thru-hull fittings into the base and standard in-line valves on top
• Provides a safe and sturdy assembly by spreading the load across a greater area when in-line valves are used as seacocks
• Prevents valve damage during OEM engine or generator installation by allowing the valve to be installed later
• Simplifies future valve replacement and maintenance

This adaptor features 1-1/2" NPS threads on the bottom and 1-1/2" NPT threads on the top. The IBVF1500 is designed for marine applications where thread compatibility and structural integrity are essential for safe below-waterline installations. Not to be used in potable water systems.
