<h3>Sierra: Six Decades of Marine Aftermarket Excellence</h3><p><strong>Sierra</strong> has spent nearly 60 years earning its reputation as one of the most trusted names in the marine aftermarket industry. Originally focused on engine and drive components for boats, the brand has grown into a comprehensive source for nearly everything a boater needs to keep their vessel running at its best — from precision instrumentation to complete engine rebuild hardware.</p><p>Now operating as a brand of Dometic, Sierra manages global aftermarket distribution from a 300,000 sq. ft. facility in Litchfield, Illinois. The Sierra brand today encompasses not only its flagship marine parts line but also well-established marine names like Shields and Moeller, offering boaters a broader catalog than ever before. Whether you own an outboard, inboard, or sterndrive, Sierra's engineering team designs products to meet or exceed OEM specifications.</p><h3>Precision Instrumentation You Can Trust on the Water</h3><p>One of Sierra's most recognized product areas is its marine instrumentation lineup. The brand's <a href="/7570-sierra-gauge-set-1480">gauge sets</a> cover everything from classic analog instrument clusters to advanced digital multi-function displays. Sierra offers packages suited to outboards, sterndrives, and gasoline-powered inboards, with options ranging from coordinated analog kits in styles like Arctic, Eclipse, and Amega to modern touchscreen solutions like the R3 multi-function gauge. Features such as scratch-resistant domed glass lenses, silicone-dampened pointers, and perimeter backlighting make these instruments highly readable in all conditions.</p><p>Behind every accurate gauge reading is a properly calibrated sending circuit. Sierra's <a href="/7570-sierra-gauge-resistor-47908">gauge resistors</a> are a critical part of that chain, ensuring the signals from sensors and sending units are correctly interpreted by your instruments. These components are built to marine-grade standards to resist moisture, vibration, and corrosion — the realities of life on the water.</p><h3>Engine Internals Built to OEM Standards</h3><p>Sierra's history in marine power is perhaps best demonstrated by its deep catalog of engine components. The brand's <a href="/7570-sierra-engine-gasket-set-5404">engine gasket sets</a> cover a wide range of outboard and inboard applications and are engineered to deliver reliable seals in the demanding thermal and chemical environment of a marine engine. For boaters performing seasonal overhauls, top-end rebuilds, or full engine restorations, Sierra gasket kits are a go-to resource trusted by professional marine technicians and DIY boaters alike.</p><h3>A Complete Marine Parts Partner</h3><p>Beyond instrumentation and engine internals, Sierra's catalog spans fuel systems, electrical supplies, steering components, shore power, and more — all covered by what the brand calls an industry-leading warranty. Sierra also maintains a comprehensive parts-finder tool that enables cross-referencing with OEM part numbers from major manufacturers including Mercury, Yamaha, Suzuki, Volvo Penta, and others, making it straightforward to find the right replacement part for virtually any application.</p>

Product Details

The Sierra Shields Vinylvent Series 400/402 is a flexible PVC ducting hose engineered for marine bilge ventilation applications. Constructed with a PVC jacket supported by an anodized wire helix, this hose delivers the structural rigidity needed to maintain airflow through tight routing paths while remaining lightweight and easy to work with aboard any vessel.

This hose is self-extinguishing when exposed to sparks or flame, making it a safe choice for bilge compartments where fuel vapors may be present. Its flexibility and anodized wire support allow it to make tight bends without kinking, ensuring consistent airflow from blower to vent outlet.

Key Features:

  • PVC construction reinforced by an anodized wire helix for shape retention and flexibility
  • Self-extinguishing — will not support flame, ideal for fuel vapor environments
  • Corrosion-resistant materials suitable for demanding marine environments
  • Resistant to UV exposure and ozone degradation
  • Primarily designed for bilge fume and gas ventilation systems
  • 3-inch inner diameter — compatible with standard inline marine blowers
  • 50-foot bulk pack for flexible installation and custom length cutting
  • Available in white (Series 400) and black (Series 402)

Sold as a 50-foot bulk pack, this hose can be cut to the exact length required for your installation. Compatible with standard 3-inch inline bilge blowers commonly found on power and sailboats. Sierra International part number 116-400-3000W; also cross-references as Series 400/402.
