Where can I find the 3/8 barb thru hull fittings in white plastic? replacing all mine and can not for the life of me find a replacement- option 2 is just get 2 nuts and double nut the old ones that lost the outside heads.. thread is m12 fwiw- can just get 2 nylon nuts, but not sure if i have enough left to go thru hull with nut on both sides..

A picture is worth 1000 words.

SeaChoice thru hulls found at most places, even local hardware stores here.

well i can find any size 1/2 up - nothing for 3/8...

My bad, my dimly lit brain read different than the 3/8 you typed.

Well here’s a 1/2”. There’s all kinds around here. I had a hard time not finding white plastic. But I always use the biggest thing I can for volume. If u can’t find the perfect thing. I’d run hose from whatever to size splice to what’s close.
