Long-lasting corrosion protection, thanks to marine-grade 316 stainless steel

Marine-grade 316 stainless steel offers high resistance to chloride-induced corrosion, and the polished surface reduces crevices where corrosion can begin. Descriptions state the material is strong and tough, not easily damaged or corroded.

Trusted material choice means reduced corrosion risk in salt water environments, lowering maintenance frequency. Expect a fitting that keeps its finish and structural integrity in regular marine use.

Quick installation and neat fit, with compatibility for common diesel parking heaters

Compatibility is listed for Webasto, Planar, Eberspacher and certain Chinese diesel parking heaters, and the design is described as easy to install without complicated tools. The straight orientation simplifies alignment with existing exhaust runs.

Fitting saves time during installation, useful when retrofitting heaters or replacing worn outlets. Suitable for owners seeking a straightforward swap-in part without specialist equipment.

Improved exhaust routing and heat management, with increased pipe clearance and thermal insulation

Labelled as a through-hull pipe fitting that increases pipe clearance and provides thermal insulation, the design reduces direct contact between hot exhaust components and surrounding materials. The straight fitting form helps maintain a clear exhaust path.

Cleaner routing helps prevent heat-related damage to nearby components and makes servicing easier. The increased clearance reduces the chance of kinking or compression at the hull penetration.
