Attwood Stainless Thru Hull Fitting
Item: 36003-100
These stainless steel thru hull fitting are the perfect addition if your boat uses stainless steel for the factory ballast fittings. This is the OEM (Original Equipment Manufacturer) fitting used on many Mastercraft, Nautique, and Tige models, amongst others, which means it will match your factory fittings perfect, because it's the exact same part (please verify that this fitting matches what is actually on your boat prior to ordering).
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" and 1-1/8" ballast hose. Perfect for finishing your integrated ballast system, or for upgrading the look of your factory through hull fittings.

Great quality and looks professional
Fantastic product that looks like factory equipment. Modified my smaller thru-hull bilge pump fitting and glued it into the 1 inch hose. Used another one of these 1 inch fittings so I now have three matching on the port side and two matching on the starboard side

Great quality and looks awesome
These are so nice I had to order three, one for the front ballast, one for the rear and another to replace the cheap plastic one for the bilge that was on my boat. These are heavy duty, look great and are easy to install. Highly recommended!

Looks clean and professional
Used these to plumb my new ballast system, not only do they look great but they are easy to install. Looks factory, I even upgraded the old plastic thru hull for the bilge pump, really updates the look of my Malibu.

Huge improvement in appearance
I changed out the factory plastic through hull fittings with these and they fit in perfectly. They were easy to install and the upgrade looks so much better than what was there. It is a cheap and easy way to upgrade the appearance of your boat.
