The American Boat and Yacht Council (ABYC) and other industry standards and regulations require the use of a seacock on
certain types of applications to stop the entry of seawater in the event of a leak in the cooling system. Refer to applicable
standards and regulations for specific requirements. The seacock also allows the seawater to be shut off when servicing the
engine.
