GROCO 3/4" NPS NPT Combo Bronze Thru-Hull Fitting w/Nut

The GROCO 3/4" NPS NPT Combo Bronze Thru-Hull Fitting w/Nut is an essential component for reliable through-hull plumbing on serious fishing and cruising vessels. This fitting is designed for applications such as seawater intake for cooling systems, raw-water washdown, and livewell circulation, making it a vital part of any boat's plumbing system.

Constructed entirely from bronze, this fitting is built to withstand the harsh marine environment, resisting corrosion in both saltwater and freshwater. Its 3/4" size is suitable for moderate flow rates typical of galley systems and engine cooling loops, ensuring efficient operation without backpressure issues. The NPS/NPT combo design allows for compatibility with various thread standards, enhancing its versatility.

Ideal for boat builders, restoration specialists, and boat owners upgrading their plumbing systems, this fitting ensures compatibility across multiple standards. The included nut secures the fitting from the interior of the hull, while the flange seats against the hull exterior, effectively distributing load and preventing leaks. This combination of features makes the GROCO fitting a reliable choice for anyone spending extended time on the water.
