T-H Marine TH-750 Straight Thru-Hull Fitting, 3/4 Inch Hose, Black

The T-H Marine TH-750 is a straight thru-hull fitting built to pass a hose through the hull below or at the waterline, commonly used for bilge pump discharge, livewell fill and drain lines, washdown systems, and other below-deck plumbing runs. It is molded from virgin plastic material for consistent sizing, extra durability, and a clean appearance, and the material is UV stabilized so the fitting resists sun exposure and holds its color and strength over time in an outdoor marine environment. The hose barb end is engineered to match standard 3/4 inch marine hose dimensions so hose slides on and seats securely, helping installations stay leak-free. This fitting is finished in black and is designed as a straight-through fitting rather than a 90 degree elbow, making it a straightforward drop-in for through-hull plumbing runs that do not require a bend. Because it is a molded, one-piece plastic design, it installs with standard hull hardware and does not require special tools beyond a hole saw sized to the fitting's flange and a marine sealant for the mounting surface.
