Even though the boat thru-hull fittings and scuppers on your vessel help keep it afloat, many builders still "cheap out" in this area. If you need to replace them we carry many original boat thru-hull fittings along with better quality upgrades. All of our plastic and stainless-steel boat scuppers have barbs to fit marine hose (cheaper industrial fittings will be slightly larger and hard to get on the hose because industrial hose runs larger than marine hose).
Please keep in mind that (except for a few exceptions) plastic boat thru-hull fittings and scuppers should only be used above the waterline.
Don't see the marine thru-hull fitting or scupper you need? We can get them in any thread or barb combination from 1/2" to 2", so contact us and let us know what size you need!
