Plumbing
Plumbing components are the core of safe and reliable water systems on board. This category focuses on critical parts that control, protect and manage water flow through the hull and onboard installations.
At Seashop, our plumbing range includes through-hull fittings, ball valves, non-return valves, vented loops, water strainers and drain plugs. These components are used in seawater intakes, discharges, cooling systems and other essential onboard installations where safety and reliability are crucial.
All plumbing products are designed for marine use and suitable for freshwater and seawater applications. They form the foundation of onboard systems and are typically combined with hoses and hose fittings, which are listed separately under Hoses.
