Note: This self-draining threaded drain plug is designed to fit 1-inch threaded drain ports and is suitable for inboard installation only. It replaces threaded plugs only; it cannot be used if the original plug is rubber.
Simple Installation: Directly replaces the original threaded drain plug without the need for tools. Installation takes less than a minute.
Design: Features a reliable ball check mechanism, eliminating the need for tear-prone rubber flaps. Engineered for saltwater environments, it drains at a rate of approximately 1-2 gallons per minute.
Installing this self-draining plug continuously removes deck and compartment water while the vessel is underway or being launched/hauled via trailer/lift.
It automatically drains during rainfall, preventing bilge pumps from draining batteries and protecting the hull, lift, and bulkheads from water damage.
