Trident Hose

<h3>Trident Marine: Purpose-Built Hose Solutions for Boaters Worldwide</h3><p><strong>Trident Marine</strong> has been a trusted name in the marine industry since 1985, building a reputation for producing hoses and fluid-handling systems that stand up to the unique demands of life on the water. From small recreational vessels to premium superyachts, Trident's product lineup covers virtually every fluid and gas routing application found aboard a modern boat — all engineered to meet or exceed rigorous industry standards including SAE, ABYC, and NMMA certifications.</p><p>What sets Trident apart is the breadth and depth of their marine-specific engineering. Rather than adapting industrial hose products for marine use, Trident designs its hoses from the ground up for saltwater exposure, engine heat, fuel and exhaust gases, and the constant vibration and flexing that boats endure. The result is a product line that marine professionals and serious boaters consistently rely on.</p><h3>A Complete Marine Hose Ecosystem</h3><p>Trident's catalog covers nearly every onboard application. Their LPG product accessories — including high-pressure thermoplastic LPG hoses, regulators, solenoids, cylinders, and roto-molded propane lockers — form a complete marine LP gas system, fully assembled and leak-tested from the factory. Whether you&apos;re outfitting a galley grill or an onboard cooking system, Trident's LP gas components are built to resist corrosion, stress, and fatigue in demanding marine environments.</p><p>For below-the-waterline and sanitary systems, Trident's sanitation hose line — including the well-known Sani Shield series — is specifically engineered for head and holding tank connections, with a construction designed to resist odor permeation and keep your cabin environment fresh. These are premium-grade hoses designed for the most challenging onboard plumbing applications.</p><p>Engine exhaust systems demand hoses that can handle high temperatures, constant flexing, and exposure to cooling water simultaneously. Trident's wet exhaust hose range includes everything from straight EPDM rubber hoses to corrugated flexible designs and silicone high-temperature variants rated up to 350&deg;F (177&deg;C) with 4&ndash;6 ply polyester reinforcement — a configuration that has become the standard aboard many premium yachts worldwide.</p><p>Beyond these specialties, Trident's broader <a href="/7617-trident-hose-hoses-200539">hose</a> catalog spans engine water and coolant, potable water, steering, speedometer, conduit, wash-down, vent ducting, and more — making it possible to source nearly every hose type on a vessel from a single trusted manufacturer. And for cockpit and livewell systems, Trident's bilge and livewell hose products deliver the durability and flexibility that fishermen and cruisers alike depend on to keep their bilge and fish-care systems running reliably.</p><h3>Why Boaters Trust Trident</h3><p>Trident Marine distributes its products to the marine market worldwide through a broad network of dealers and marine supply companies. Their products carry certifications and type approvals from recognized bodies including Lloyd's Registry, ensuring that quality isn&apos;t just a claim — it&apos;s independently verified. Whether you&apos;re a DIY boater, a professional boat builder, or a marine service yard, Trident hoses offer the peace of mind that comes from decades of proven, purpose-built marine engineering.</p>

Product Details

The Trident TRS-435 Reducer Sleeve provides a reliable solution for connecting hoses of different inside diameters in marine exhaust and cooling systems. This reducer transitions from 4 inches to 3.5 inches, allowing you to adapt elbows, bellows, and other exhaust components where two different ID sizes are required.

Key Features:

  • Reduces from 4" ID to 3.5" ID for versatile hose connections
  • Constructed from durable EPDM rubber for long-lasting performance
  • Slides into one end of exhaust elbows or bellows for secure fit
  • Designed for marine wet exhaust and cooling applications
  • Flexible material accommodates minor misalignment

This reducer sleeve simplifies installation when transitioning between different hose sizes in your marine exhaust system, eliminating the need for custom fabrication. The EPDM rubber construction provides excellent resistance to heat, ozone, and weathering for reliable service in demanding marine environments.
