Marine-Grade Bilge Ventilation Hose β UV-Resistant PVC with Anodized Wire Helix, Black
The Shields Marine Series 400/402 Vinylvent is a flexible PVC ducting hose reinforced with an anodized wire helix for shape retention and crush resistance. Designed for marine bilge ventilation, it safely channels engine compartment gases and bilge fumes away from enclosed spaces β a critical safety function on any gasoline-powered vessel.
This listing is for a 3-foot cut section in black β ideal for short runs, repairs, or replacing a damaged section of existing ventilation hose without buying a full roll. The black finish blends cleanly into engine compartments and bilge spaces.

Parts Desk Insights
Best Use Case: The 3-foot black section is the right sell for customers replacing a short damaged run of blower hose where appearance in the engine compartment matters, or for professional installers who prefer black hose for a cleaner finished look. Itβs also a practical upsell when a customer is buying a replacement blower motor β if theyβre pulling the old blower, the hose is often brittle and worth replacing at the same time.
Black vs. White: Functionally identical β the colour choice is purely aesthetic. Black is generally preferred in engine compartments for a professional finish and because it hides grime better over time. White is easier to inspect for cracks during routine maintenance.
Ventilation Compliance: ABYC and Transport Canada standards require powered ventilation for gasoline-engine compartments. This hose is appropriate for use with a 3" blower in compliant ventilation systems. Customers building a full system will also need a blower motor, through-hull vent fitting, and stainless hose clamps.
