<h3>About Marine Products International (MPI)</h3><p>Marine Products International — widely known in the boating world as <strong>MPI</strong> — has been a trusted name in rubber and plastic marine hose for the recreational boating industry since 1981. Operating out of Eastlake, Ohio, MPI has spent more than four decades engineering hose and plumbing solutions that keep engines cool, exhaust gases safely routed, and onboard plumbing systems leak-free. Their products are found on vessels ranging from weekend runabouts to performance inboards, and MPI consistently ranks among the top choices of U.S. boat manufacturers at the OEM level.</p><p>What sets MPI apart is a commitment to independent product testing and strict adherence to — and often exceeding of — industry standards set by organizations such as the SAE, USCG, and NMMA. Whether a boater needs a hose that stands up to hot exhaust gases, resists ozone degradation, or handles the vibration and panting of a working marine engine, MPI engineers their products to outlast the conditions they're built for.</p><h3>MPI Exhaust Hose</h3><p>The core of MPI's catalog is their extensive line of <a href="/13010-marine-products-international-exhaust-hose-13424">exhaust hose</a>. Available in both hardwall and softwall configurations, MPI exhaust hose is designed for reliable performance in the demanding environment of a boat's engine room. Hardwall variants handle longer runs where structural rigidity matters, while softwall options are ideal for short, straight connections. Each type is built to resist exhaust fumes, ozone, mild chemicals, and elevated temperatures.</p><h3>Wet Exhaust Systems</h3><p>MPI's <a href="/13010-marine-products-international-wet-exhaust-hose-201177">wet exhaust hose</a> is one of their most recognized product lines. Wet exhaust systems mix raw cooling water with engine exhaust gases to reduce heat before expelling them overboard — a setup used on the vast majority of recreational inboard and sterndrive boats. MPI's wet exhaust hose is engineered with double the ozone resistance required by SAE J2006 standards and is available in softwall, hardwall, and corrugated profiles to suit any routing challenge.</p><h3>Nylon Pipe &amp; Hose Fittings</h3><p>A hose system is only as reliable as the fittings that connect it. MPI's lineup of <a href="/13010-marine-products-international-nylon-pipe-hose-fittings-200724">nylon pipe &amp; hose fittings</a> provides lightweight, corrosion-resistant connection points that hold up in the wet, chemically active environment inside a boat's hull. Nylon fittings are particularly valued in freshwater, sanitation, and livewell plumbing runs where metal corrosion is a concern.</p><h3>Plumbing Parts &amp; Accessories</h3><p>Beyond hose, MPI offers a range of <a href="/200786-plumbing-parts-accessories-marine-products-international-13010">plumbing parts &amp; accessories</a> that complete a boat's onboard fluid management system. These components work in concert with MPI's hose lines to give boat builders and do-it-yourself owners a cohesive system from a single trusted manufacturer.</p><h3>Marine Hoses</h3><p>MPI's broader catalog of <a href="/13010-marine-products-international-hoses-200539">hoses</a> spans applications including water system hose, sanitation hose, bilge hose, and PVC corrugated hose. Each product category is backed by independent testing and the same engineering philosophy that has made MPI hose a staple on production boats across the country. When routine maintenance calls for a hose replacement, choosing the right MPI product ensures a fit and service life that meets the original build specification.</p>
