90° THROUGH-HULL FOR 29 MM HOSES.

Function and technical context

The 90º through-hull for 29 mm hoses is a sealing accessory that allows the passage of a hose through the hull of the boat with a change of direction of 90 degrees, guaranteeing a hermetic seal at the point of penetration of the hull. It usually works in seawater cooling, bilge evacuation, exhaust or water intake systems, being the element that prevents water from entering the interior of the hull at the points where the pipes cross the lining. Its correct installation is critical for the safety of the boat: a thru-hull in poor condition or poorly installed can cause uncontrolled entry of water, with the consequent risk of flooding. The 90º elbow of this reference THTH-1290CP facilitates the layout of the installation in small spaces where a straight exit is not viable, allowing an orderly conduction without tensions in the hose.

When to replace this part?

The thru-hulls must be visually inspected at each docking or seasonal maintenance, paying special attention to the presence of microcracks, deformations, galvanic corrosion on the body or deterioration of the perimeter sealing, symptoms that indicate that the component has lost its sealing capacity. If persistent moisture is detected around the installation point, water oozing or difficulty in correctly tightening the lock nut, replacement should be carried out immediately. Replacing the thru-hull preventively during the annual beaching, before obvious symptoms of failure appear, is the practice recommended by professionals in the sector to avoid emergency situations in navigation.
