Forespar Marelon® Marine Plumbing offers durable, lightweight, and internationally approved underwater systems that will provide you with years of hassle-free, non-corrosive, and electrolysis-free use.

Marelon® is the contemporary substance utilized in marine plumbing systems. Its unique blend of polymer composite compounds, including resins and additives, creates an extremely strong marine-grade product that is a non-corrosive proprietary formulation and does not experience the same degradation as traditional bronze marine plumbing components.
