Attwood Common Size Stainless Thru Hull Fitting
With most ballast systems using 1" or 1-1/8" hose to maximize speed these thru-hull fittings make it easy to get a perfect match with existing 3/4" thru-hull connections (used for the bilge pump or existing ballast). Available in 3/4", 1" and 1-1/8" internal hose barb connections with the exact same external dimensions, you can have matching thru-hull connections for everything in the boat, but use either 3/4", 1" or 1-1/8" hose depending on the application.

This family of fittings is identical on the exterior, so what you see outside the boat will be exactly the same, no matter which size hose you connect to on the inside. If you suffer from OCD, this is the thru-hull connector that you've been looking for.
Suitable for use as a drain or vent fitting for above the waterline, the extended length barb has plenty of surface area to create a leak-proof connection to standard 3/4", 1" or 1-1/8" ballast hose while the compact size makes it easier to make hose connections, even in cramped locations. Perfect for finishing your integrated ballast system, or for upgrading the look of your factory thru-hull fittings.
