Thru Hull with Hose Tail Plastic 3/4" - 19 mm

Function and technical context

The thru-hull with spigot is a naval plumbing accessory that allows water pipes or hoses to be routed through the hull of the boat in a sealed manner, preventing water from entering the interior. Made of white plastic with high resistance to marine corrosion, this model incorporates a 3/4" thread and a 19 mm outlet, which makes it compatible with standard hoses for refrigeration circuits, bilge drain, water intakes or drains. Its correct installation is critical for the integrity of the boat: a deteriorated or poorly sealed thru-hull can cause progressive leaks that, if not detected in time, compromise the safety of the boat and its crew.

When to replace this part?

The most common symptoms that indicate the need to replace a thru-hull are the presence of moisture or dripping around the penetration point of the hull, visible deformations in the plastic due to aging or prolonged exposure to UV rays, and loss of tightness in the thread or at the connection with the hose. It is recommended to visually inspect all thru-hulls at each seasonal tune-up, paying special attention to the condition of the material, joints and tightening. Preventively replacing a thru-hull in poor condition during stranding is a simple and economical measure that avoids risky situations and serious navigational breakdowns.
