Trident Marine

<h3>About Trident Marine</h3><p><strong>Trident Marine</strong> holds a distinction few manufacturers can claim: it is the oldest North American marine hose company. Founded in 1985, Trident Marine has focused on producing hoses that excel in durability, performance, and reliability. That decades-long track record has made the brand a go-to choice for boat owners, marine professionals, and commercial operators who need hose systems they can genuinely trust on the water.</p><h3>A Full-Spectrum Marine Hose Manufacturer</h3><p>Trident Marine brings marine hose, tubing, ducting, conduit, and flexible wet exhaust connectors to the marine market worldwide. Trident Marine also builds and supplies Marine LP Gas Systems. This breadth of product coverage means a boater can source nearly every hose and fluid-transfer need from a single, trusted manufacturer rather than piecing together solutions from multiple suppliers.</p><p>At the core of the Trident lineup is an extensive range of marine hoses. Product categories include fuel, sanitation, potable water, bilge/live well/drain, engine water, steering &amp; fitting, speedometer, conduit &amp; flanges, vent duct &amp; A/C ducting, commercial, and wash-down hose — alongside a full wet exhaust line and a complete LPG system offering.</p><h3>Wet Exhaust Hose</h3><p>One of the brand&apos;s signature product lines is its <a href="/14870-trident-marine-wet-exhaust-hose-201177">wet exhaust hose</a> selection. Trident offers extra-flexible corrugated marine wet exhaust hose for longer connections with substantial bends, as well as silicone marine wet exhaust and water-coolant hose in extra-thick soft-wall silicone construction. Their silicone marine wet exhaust hoses are available in various sizes and colors, including Glossy Blue, which features 4–6 ply polyester reinforcement and a maximum operating temperature of 350°F (177°C).</p><h3>Sanitation Hose</h3><p>Keeping a vessel&apos;s head and holding tank system odor-free is a constant concern for boaters, and Trident&apos;s <a href="/14870-trident-marine-sanitation-hose-200897">sanitation hose</a> lineup addresses that challenge head-on. Trident A1 marine sanitation hoses like the Sani Shield are designed for head and holding tank connections, engineered to resist odor permeation. This makes them a practical upgrade for any vessel where comfort and cleanliness matter.</p><h3>Fuel Hose</h3><p>Fuel system integrity is non-negotiable in any marine application. Trident&apos;s fuel hose is engineered to meet strict industry standards, providing superior resistance to harsh marine conditions, fuel degradation, and temperature extremes. Trident Marine hoses meet or exceed major industry standards such as SAE J1527 for fuel hoses, ISO quality standards, and other marine-specific certifications ensuring safety and reliability. Shop <a href="/14870-trident-marine-fuel-hose-bulk-200443">Trident fuel hose in bulk</a> to keep your vessel&apos;s fuel system running safely.</p><h3>Hose Clamps &amp; Fittings</h3><p>A hose system is only as reliable as its connections. Trident rounds out its lineup with purpose-built hardware: Trident Marine&apos;s T-Bolt clamps provide a strong, secure union for critical installations. The brand also stocks solid brass standard hose fittings, ferrules, and pipe adapters in all fuel hose sizes. Whether you need <a href="/14870-trident-marine-hose-clamps-200536">hose clamps</a> or <a href="/14870-trident-marine-nylon-pipe-hose-fittings-200724">nylon pipe and hose fittings</a>, Trident offers complementary hardware designed to work seamlessly with its hose products.</p>
