GROCO IBVF-1500 Patented Bronze Flange Adapter, 1-1/2" NPS to NPT

Ensure secure and compliant marine plumbing connections with the GROCO IBVF-1500 Patented Bronze Flange Adapter. Engineered to eliminate the dangerous thread mismatch commonly encountered when installing NPT in-line valves directly onto NPS-threaded thru-hulls, this adapter provides a safe and sturdy foundation for your vessel's critical systems. Proudly featuring a patented design and constructed from durable C83600 bronze, it offers superior corrosion resistance and long-term reliability in harsh marine environments. Upgrade your boat's plumbing for enhanced safety and easier maintenance.

Key Benefits & Features:

• Patented Design: Offers a unique, engineered solution to prevent dangerous thread mismatch between tapered NPT valves and straight NPS thru-hulls.
• Premium C83600 Bronze Construction: Provides exceptional strength and superior corrosion resistance, ensuring longevity in demanding saltwater and freshwater applications.
• 1-1/2" Thread Adaptation: Seamlessly converts 1-1/2 inch NPS (National Pipe Straight) thru-hull connections to 1-1/2 inch NPT (National Pipe Tapered) for in-line valves, standardizing your plumbing interface.
• Enhanced Safety: Creates a safe and sturdy assembly when in-line valves are used as seacocks, distributing loads more effectively than direct threading.
• Simplified Installation & Maintenance: Designed to accept standard thru-hulls at the base and standard in-line valves on top, simplifying initial setup and facilitating future valve replacement, even potentially while afloat.
• OEM Protection: Helps prevent valve damage during engine or generator installation, offering peace of mind for both new builds and upgrades.

Recommended Usage: Ideal for use in marine raw water systems, engine cooling, livewells, and other critical plumbing applications requiring a robust and secure thru-hull connection.
