PLASTIC PLUMBING FITTINGS Elbow thru-hull fittings Elbow thru-hulls are the answer to the most common plumbing issues : • Allow major room saving, as they can be used with a hose running along the hull. • Avoid making a bend in the hose, which can sometimes be a source of leak or breakage. • Require a simplified installation process inside the hull, carried out by one person only. You can hold it firmly with one hand, while screwing with the other hand. Overall depth (A) Hose Ø (B) Int. Ø Cut-out Ø (D) depending on hull thickness (C) Ext.
