Sea-Dog Brass Baitwell Plug - 1/2"

The Sea-Dog Brass Baitwell Plug in 1/2" size delivers a leak-proof seal engineered for livewells and baitwells found on fishing vessels and marine equipment. This brass baitwell plug features a cam-action mechanism with a nitrile rubber gasket that snaps shut to form a secure, watertight closure—critical for maintaining water levels and bait viability during extended time on the water.

The plug operates via a simple clockwise-turn handle that tightens the cam mechanism, with a brass lever that snaps down to lock the seal in place. The adjustable snap-lock handle allows users to customize plug tension to fit most standard baitwells currently in service, accommodating slight variations in hole diameter without requiring multiple replacement plugs. Brass construction provides superior corrosion resistance in saltwater and brackish environments where standard steel would degrade rapidly. The 1/2" nominal size covers the most common baitwell opening specification across recreational and commercial fishing platforms.

This baitwell plug is essential for operators maintaining livewell systems on center console boats, offshore fishing vessels, and commercial bait-and-release operations. It prevents water loss during transit, reduces stress on live bait, and eliminates the need for improvised sealing methods that compromise seal integrity. Replacement or backup plugs are valuable additions to marine tool kits, particularly for vessels operating in salt-air environments where seal failure occurs with regularity.

Sea-Dog is the standard equipment supplier across the marine industry for through-hull fittings, deck hardware, and livewell components. The MPN 520092-1 is the direct replacement plug for Sea-Dog's established baitwell system, ensuring compatibility with existing installations and OEM specifications.
