Moeller Drain Plugs, Tubes & Accessories

Moeller Drain Plugs, Tubes & Accessories: OEM-Trusted Protection for Your Boat

When water needs to stay out — or drain out cleanly — the integrity of your boat's drain system is non-negotiable. Moeller Marine Products has spent decades earning its place as one of the most trusted names on the water, and their line of drain plugs, tubes, and accessories reflects that same commitment to precision engineering and lasting durability.

For more than 25 years, Moeller Marine Products has been the industry standard in fuel system design and construction, with a reputation built on innovative engineering, quality construction, and award-winning service. That same philosophy carries directly into their drain hardware — components that boat builders and weekend boaters alike depend on to keep hulls sealed and bilges dry.

A Complete Drain System Ecosystem

What sets Moeller apart in this category is the cohesion of their system. Rather than offering standalone components, Moeller Marine Products produces flanged brass drain tubes, flanged aluminum drain tubes, flanging tools, motorwell drain tubes, transom drain tubes, and a full range of aftermarket drain tube products. Every piece is engineered to work together.

At the heart of Moeller's drain plug lineup are their proprietary plug families. Their transom drain tubes are designed for use with Moeller's Snap-Tite, Turn-Tite, and Trail-n-Bail plugs — including their well-known Snap-Tite® and Turn-Tite® boat bailer plugs. This compatibility-focused design means you can mix and match within the Moeller ecosystem with confidence, knowing every part was built to fit the next.

Brass and Aluminum Options for Every Application

Moeller offers drain tubes and fitting kits in both brass and aluminum, giving boaters the flexibility to match hardware to their hull's construction. Their special alloy brass drain tubes are flanged 90 degrees on one end to function as a drain for the transom, motor well, live well, or baitwell, and are designed for use with Moeller's Snap-Tite, Turn-Tite, and Trail-n-Bail plugs — with the general guidance to pair brass drain tubes with brass plugs and aluminum drain tubes with aluminum plugs.

Drain tubes are available in 1-inch and 1-1/4-inch diameters, in both brass and aluminum, and in lengths ranging from 1-7/8 inches to 15 inches to accommodate thicker transoms. This range of sizing options ensures a proper fit whether you're working on a compact aluminum fishing boat or a larger fiberglass hull.

OEM-Certified Quality You Can Count On

Moeller's drain tube products are widely regarded as an industry benchmark for quality and durability, and carry OEM certification. As a manufacturer of rotationally molded, injected, and thermoformed parts, Moeller designs and supplies components for boat builders and marine enthusiasts across the recreational marine industry. That OEM-level pedigree means the drain hardware you install meets the same standards as what came on your boat from the factory.

For boaters who want a complete installation solution, Moeller also offers the Aluminum Drain Fitting Kit and dedicated flanging tools, with installation requiring a Drain Fitting Kit and flanging tool for a proper, watertight fit. From replacement plugs sold in multi-packs to full garboard drain plug kits, Moeller makes it straightforward to service or upgrade your entire drain system in one go.
