Raw Water Strainers and Accessories
Boat owners depend on seawater to operate many boat systems — but they need a way to prevent dirt, sediment, crustacean shells and other debris from getting into those systems. A marine sea strainer catches those particles before they can reach the water pump, helping equipment last longer and perform better. We offer a variety of seawater strainer kits to protect engines, air conditioners, generators, livewells and more. Boat owners can always get the correct parts from our extensive catalog and enjoy free U.S. shipping on orders over $100.
Protect Your Boat with Seawater Filtration
Sea strainers come in several designs with NPT or barbed fittings for secure connections. Those fittings range from 1/2-inch to 2.5 inches or more depending on the lines or hoses you’re using. Durable materials such as bronze, stainless steel and polyethylene resist saltwater corrosion — and the filters are fully serviceable to extend their operating life. Specialty components include cooling water strainers to lower temperatures and special bilge water strainers for these heavy-duty pumps. Trust the leading marine plumbing brands such as Groco, Sherwood, Perko, Vetus and Jabsco.
