Sea-Dog Drain Tube 520320-1, HDPE, White, Adjustable for Motorwell, Livewell, and Baitwell Drains

The Sea-Dog Drain Tube (520320-1) removes water and other fluids from motor wells, livewells, and baitwells, giving boat owners a simple, leak-proof way to keep these compartments dry. It is constructed of durable, impact-resistant injection molded HDPE, a material chosen for its resistance to cracking and corrosion in the wet, high-exposure environments where drain fittings are used.

The tube is flanged 90 degrees on one end and is designed to fit standard 1 inch diameter mounting holes, giving it a clean, finished look once installed. Its adjustable length accommodates bulkhead installations ranging from 3/4 inch up to 2-1/2 inches thick, so it fits a range of deck and hull thicknesses without needing to be cut or modified. A locking drain tube nut threads down to create a tight, leak-proof seal against the bulkhead, and because the tube telescopes to length, no flaring tools are needed during installation, which saves setup time compared to fixed-length tubing.

This drain tube is designed for use with snap handle and T-handle drain plugs, making it a straightforward fit for common livewell and baitwell drain plug setups. It is finished in white; Sea-Dog also offers this same drain tube design in black ABS for buyers who want a different material or color to match their boat's fittings.
