Ensure robust and compliant marine plumbing connections with the GROCO IBVF-1000 1" Bronze NPS to NPT Flange Adapter. This patented adapter is expertly designed to resolve critical installation challenges in the marine industry, particularly the dangerous thread mismatch that can occur when connecting NPT in-line valves to NPS thru-hulls. Backed by Groco's 100+ years of American manufacturing excellence, it provides a safe, sturdy, and reliable foundation for your vessel's seacock assemblies.

Key Benefits & Features:

• Superior Material Construction: Crafted from durable C83600 bronze for exceptional corrosion resistance and long-term reliability in harsh saltwater environments.
• Eliminates Thread Mismatch: Specifically engineered to adapt 1" NPS (National Pipe Straight) threaded thru-hulls to 1" NPT (National Pipe Taper) threaded in-line valves, preventing dangerous cross-threading and ensuring a secure fit.
• Enhanced Seacock Safety: Provides a sturdy and structurally sound assembly when in-line valves are used as seacocks, distributing loads more effectively and meeting the stringent ABYC H-27 standard for marine plumbing.
• Simplified Installation & Replacement: Facilitates easier future valve replacement and allows OEMs to install valves later, preventing potential damage during engine or generator installation.
• Versatile Compatibility: Designed to accept standard thru-hulls at the base and standard in-line valves on top for flexible system integration.
