Description

SHIELDS Black Heavy-Duty Vinyl Blower Hose 3″ – 420-3″

The SHIELDS 420-3″ Black Heavy-Duty Vinyl Blower Hose is designed for marine ventilation systems, including bilge blower ducting and engine compartment fume extraction. Built from heavy-duty black PVC with a crush-resistant helix, this hose provides flexible routing while standing up to ozone, weather, UV exposure, and the harsh marine environment.

• 3″ inside diameter fits common marine bilge blowers and ventilation fittings
• Heavy-duty black PVC construction for durability and long service life
• Flexible, crush-resistant helix supports airflow through tight installation runs
• Resistant to ozone, weathering, and UV sunlight
• Meets UL94V and MVSS flammability resistance / burn test criteria

This hose is suitable for venting bilge gases and fumes where a stronger, more durable alternative to light-duty vent hose is required.
