2″ Bronze Thru-Hull for High-Flow Marine Systems
This Groco bronze thru-hull fitting is designed for marine plumbing installations that demand higher flow rates with reduced drag compared to standard fittings. The C83600 bronze construction resists corrosion in saltwater environments. It suits boat builders and refit yards fitting or upgrading through-hull connections on hulls and bulkheads.
Check Thread Compatibility and Hull Thickness
Verify that the NPSM and NPT combination thread matches the mating valve, seacock or hose adapter you plan to use. Confirm the hull or bulkhead thickness at the installation point allows full engagement of the supplied nut without bottoming out. Ensure the flange diameter suits the available flat surface and that the bronze alloy is compatible with existing underwater metals to avoid galvanic issues.

Questions about this item
What is included with the 2" Bronze High Speed Thru-Hull Fitting and is any additional hardware required?
The fitting is supplied with its matching nut. The NPSM/NPT combination thread mates to standard pipe threads, so no extra adapter is needed for typical installations.
When should I choose this high-speed fitting instead of a standard thru-hull?
Choose this model when maximum flow and reduced drag are priorities, such as raw-water intakes or high-volume discharge lines where the streamlined bronze profile outperforms a conventional thru-hull.
