These through hull fittings can be made as small as 1/4" all the way up to 4". These can be custom configured if you contact us. These units are straight tube with the O.D. as listed with 4" of tubing behind the flange. Use of double clamps and above waterline is recommended. 316L stainless steel, laser cut and pulse rotary welded, passivated, hand polished and post-process acid wash leads to the premier finish and longevity of these through hull fittings. These are to be attached with stainless flat head machine screws.
If threaded ends are desired, see "through hull fittings- pipe".
