Complete your ballast system installation with this OEM matching stainless steel thru-hull fitting for tight installs.

Our stainless steel thru hull fittings are the perfect finishing touch to your automated ballast system installation. If your boat has stainless steel hardware and accents from the factory and you need the convenience of a 90 degree fitting due to tight hose routing, this is the thru-hull you want. Since this is the exact same part that many of the major manufacturers in the industry, including Centurion, Malibu, Mastercraft, Moomba, Sanger, Supra and Tige install on boats from the factory, your ballast system will look like it came with the boat (please confirm dimensions provided below prior to ordering).

If your boat doesn't have stainless steel thru-hull fittings for you existing ballast system or bilge pump, this is a great choice to upgrade the exterior of your boat and get that stainless look.

Suitable for use as a drain or vent fitting for above the waterline use, the extended length barb has plenty of surface area to create a leak-proof connection to standard 3/4" and 1-1/8" ballast hose.

Perfect for finishing your integrated ballast system, or for upgrading your boat by replacing the factory provided black or white thru-hull connectors.
