1-1/4" Bronze NPS to NPT Flange Adapter

The GROCO 1-1/4" Bronze NPS to NPT Flange Adapter is a versatile and essential component designed to address common challenges in the marine industry. This adapter is crafted from durable C83600 bronze and offers a reliable solution for various applications, ensuring a secure and efficient connection between NPS and NPT threaded components.

Key Features and Benefits

The IBVF Flanged Adapters are engineered with cutting-edge technology to provide several significant advantages. Eliminate thread mismatches and enhance safety with our adapter, which prevents dangerous accidents during the installation of in-line valves onto thru hulls.
  • Accept standard thru-hulls into the base and standard in-line valves on top for seamless integration.
  • Ensure a safe and sturdy assembly when using in-line valves as seacocks, providing peace of mind for marine enthusiasts.
Additionally, this adapter is perfect for OEMs, offering the flexibility to install valves later during engine or generator installation, thereby preventing valve damage.

Specifications and Practical Uses

This adapter is not only designed for safety and flexibility but also for ease of use. With its C83600 Bronze and #316 SS models, it offers robust construction and corrosion resistance. The box dimensions are 5"H x 5"W x 5"L, weighing just 1.3 lbs, making it convenient for installation and storage. The GROCO 1-1/4" Bronze NPS to NPT Flange Adapter is ideal for marine applications, including boat construction, maintenance, and repair. Its ability to simplify future valve replacement and prevent damage during installation makes it an indispensable tool for any marine professional or DIY enthusiast.
