Sierra 116-400-3000W Shields Vinylvent Marine Bilge Blower Vent Hose 3in x 50ft White

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.
