Its designed after one Cotten built so thank you sir. Anyway I found the leak and thought it was the nipple but turns out it was the manifold. It is not 45% so it will never physically seal. Vender says they found out they hed a bad batch and will make it right, but it was driving me nuts, I checked everything.
