Thru-Hull is a fitting that is attached through the Hull of a Boat. A thru Hull fitting requires a hole to be cut/drilled in the boat hull for the fitting to pass through.

Thru hulls can be used to expel wastewater, such as from a sink, to let seawater in, such as for engine cooling or to allow placement of sensors such as depth gauges.

Here you will find the high-quality thru-hull fittings you are looking for. They’re easy to install, good looking, strong, and flexible.
For boat builders that know that a quality fit and finish pays off.
