Wire-Supported Vinyl Blower Hose for Engine Compartment Ventilation – 3" x 50' Bulk Roll, White
The Seachoice 400 Series vinyl blower hose is designed for venting bilge gases and fuel fumes from enclosed engine compartments on powerboats and inboard-powered vessels. The wire-supported construction keeps the hose open under compression and around bends, maintaining consistent airflow through the ventilation system — a critical safety requirement on gasoline-powered boats.
This listing is for a 3" interior diameter, 50-foot bulk roll in white — ideal for marine yards, service shops, or boat owners doing a full ventilation system installation or stocking hose for multiple jobs. The white finish makes it easy to inspect for cracks or deterioration during routine maintenance checks.

Parts Desk Insights
Best Use Case: The 50' white bulk roll is the right recommendation for marine yards and service shops stocking hose for multiple jobs, or for full ventilation system installations where a longer run is needed. White is preferred by some installers for easier visual inspection — cracks and deterioration are more visible on white hose than black. For customers replacing a single short run, the 3" x 10' cut length is a better fit and avoids waste.
400 vs. 402 Series: Both are wire-supported vinyl blower hose suitable for bilge ventilation. The series designation reflects minor manufacturing specification differences — both meet the same application requirements. Customers do not need to match the series number of their existing hose; fitment is determined by interior diameter.
Safety Note: Engine compartment ventilation hose must be flame-retardant per ABYC and USCG standards for gasoline-powered vessels. This hose meets that requirement. Do not substitute standard bilge hose or plain PVC in blower applications.
Cutting Tip: Wire-supported hose can be cut with a utility knife — score around the circumference and bend to snap the wire, then trim the vinyl cleanly. Secure with stainless hose clamps at each end.
