The Seachoice 18821 is a brass drain plug with a snap-lock design, purpose-built for marine drain tubes. This essential accessory provides a reliable way to drain water from your boat’s bilge or transom after a day on the water or during routine maintenance. Boaters need dependable hardware that won’t fail in saltwater environments, and this plug delivers the durability and security required for worry-free operation.
Installing and operating a drain plug from inside the transom makes maintenance simpler and faster. The snap-lock mechanism holds the plug firmly in place, preventing accidental dislodgement while you’re underway. The neoprene seal ensures a tight fit that stops leaks and protects your vessel from water intrusion.
