GROCO 2" Bronze NPS to NPT Flange Adapter

The GROCO 2" Bronze NPS to NPT Flange Adapter is a crucial component for marine applications, particularly for cruisers and commercial operators who require dependable seacock performance. This bronze adapter effectively connects National Pipe Straight (NPS) and National Pipe Tapered (NPT) threading standards, facilitating the integration of hull penetrations where different thread specifications are present.

Constructed from durable marine-grade bronze, the GROCO adapter is designed to resist saltwater corrosion, ensuring longevity in demanding marine environments. Its flanged design provides a strong mechanical connection, promoting secure face-to-face seating that minimizes the risk of leaks. The 2-inch bore allows for substantial flow rates, making it suitable for applications such as engine cooling and raw-water circulation.

Professional boat builders, marine surveyors, and experienced cruisers trust GROCO fittings for their reliability and performance. This adapter is particularly beneficial for those upgrading through-hull inlets or replacing corroded seacocks, as it eliminates the need for costly custom machining or incompatible fittings.
