Wallas Hull Lead Through Exhaust Fitting Kit for Coaxial Systems

Designed for Wallas coaxial exhaust systems, this Hull Lead-Through Kit provides a robust, watertight exit for exhaust through the boat’s hull or stern. It’s engineered to work with the 28 mm and 45 mm coaxial exhaust pipes used by Wallas heaters and cooktops, delivering a clean, ship-shape installation that resists salt spray and vibration.

In the Watercraft Exhaust Parts category, this Wallas Hull Lead-Through Exhaust Fitting Kit is a purpose-built solution for reliable exhaust routing on boats.

What’s included and how it helps your install:

• Coaxial hull through fitting (WAL 2467) that accepts the 28 mm and 45 mm exhaust tubes, ensuring a precise fit and reliable seal.
• Copper gasket and mounting hardware to create a watertight seal between hull and fitting, plus a stainless clamp and screws to secure the assembly.

Why this kit stands out

• Specifically designed for Wallas coaxial systems, compatible with popular Wallas models such as Spartan and Viking heaters, as well as 88DU cooktop and 800D stove. This focused compatibility helps ensure performance and ease of install.
• Marine-grade construction and a compact footprint make it suitable for both new builds and retrofits where space around the stern is tight.
• Part of Wallas’ official supplies and accessories lineup, which helps maintain system integrity and compatibility with other Wallas components.

Practical use and care

• Through-hull lead-throughs like 2467 are standard options in Wallas’ accessory ecosystem; consider pairing with related components such as the 5400 stern lead-through for other routing needs.
• Plan the installation using Wallas’ published guidelines for coaxial exhaust configurations to ensure safe routing and adequate clearance.
• Regularly inspect the gasket and clamps for wear and reseal if you notice any leakage or corrosion to maintain optimal exhaust sealing.

Who benefits

• Boat owners installing or upgrading a Wallas coaxial heating or cooking system that requires a reliable hull exit for exhaust.
• Marine technicians seeking a purpose-built, kit-based solution backed by Wallas’ own accessory catalog.
