Thru Hull Exhaust Skin 24mm Stainless Steel 316 - Corrosion Resistant

In this review the reviewer looks at a compact thru hull exhaust skin designed for diesel parking heaters, and finds it best suited for boat owners and installers who need a durable, low-maintenance exhaust pass-through. The biggest reason to buy is the construction: made from 316 stainless steel with a polished, corrosion-resistant surface that matches marine environments and pairs neatly with 24mm inner diameter hose pipes. Our review highlights the simple hardware package and straightforward fit for diesel parking heater installations where a robust hull fitting is needed.

Key Features

• Material strength: 316 stainless steel construction provides long-term resistance to corrosion in marine and damp environments, reducing replacement frequency.
• Polished finish: Surface polishing improves corrosion resistance and gives a clean appearance that integrates well with boat exteriors and deck hardware.
• Compatibility: Sized for 24mm inner diameter hose pipes, it works directly with common diesel parking heater exhaust hoses for an easy match.
• Included hardware: Supplied with 1 piece thru hull, 3 gaskets and 3 screws with nuts so installers have the basic parts needed to mount the fitting.
• Easy installation: Design allows straightforward install or removal using the included screws, nuts and washers, saving time during maintenance or replacement.

Who It's For

Boat owners, installers and DIY mechanics fitting or replacing exhaust outlets for diesel parking heaters will appreciate this thru hull skin for its marine-grade material and direct fit for 24mm hose. The product is especially useful where a neat, corrosion-resistant exterior fitting is desired and where installers want to avoid sourcing separate gaskets or fasteners.

Those who should look elsewhere include users with nonstandard hose sizes or systems that require welded fittings or integrated silencing; this unit is a bolt-on exhaust skin meant for 24mm hose connections and basic mounting rather than custom fabrication jobs.

Pros & Cons
