What is the difference between a seacock and a thru-hull fitting?

A seacock is used to draw seawater for engine cooling, sanitation systems, or fire fighting systems. A thru-hull fitting, on the other hand, is used to discharge grey water (shower, sink) or black water (toilet) from the boat.

Can I use a plastic seacock instead of a stainless steel one?

We advise against using plastic seacocks below the waterline. AISI 316 stainless steel offers greater mechanical and corrosion resistance, ensuring greater safety.

How can I prevent corrosion of stainless steel seacocks?

Use stainless steel-specific cleaning products and periodically check the condition of your seacocks. If there are signs of corrosion, consider replacing the component.

What type of sealant should I use to install a seacock?

Use a thread sealant specifically designed for marine applications, resistant to seawater and hydrocarbons. Avoid using silicone, which may deteriorate over time.

What diameter should I choose for my seacock?

The diameter of the seacock must be adequate for the flow rate of the pump or system to which it is connected. Consult the technical specifications of the components to choose the correct diameter.
