Trident Marine 3" Blue Polyduct Blower Hose – Sold by the Foot – 481-3000-FT
The Trident Marine 3" Blue Polyduct Blower Hose is a flexible, lightweight ventilation duct designed for use in marine blower and ventilation systems. Commonly installed in engine compartments, bilge ventilation setups, and cabin air circulation systems, this hose helps safely move air and fumes where reliable ventilation is required.
Manufactured from durable blue polyethylene ducting, this polyduct hose offers excellent flexibility for routing through tight spaces while maintaining its shape during operation. Its 3-inch diameter is compatible with most standard marine blowers and vent fittings, making it a versatile choice for new installations or replacement ducting.
Sold by the foot, the 481-3000-FT allows you to order the exact length needed, reducing waste and simplifying custom installations. The hose is resistant to moisture and common marine conditions, making it suitable for both freshwater and saltwater environments.
Trusted by boat builders and marine technicians, Trident Marine hoses are known for quality construction and long-lasting performance..

Installation Pro-Tips
-
Airflow Direction: Ensure the hose is routed as straight as possible. Every sharp bend significantly reduces the CFM (Cubic Feet per Minute) output of your blower.
-
Secure Connections: Use high-quality 316 Stainless Steel T-bolt or worm gear clamps to secure the hose to your blower and deck vents to prevent vibration from shaking it loose.
-
Avoid Low Spots: Try to avoid "traps" or low loops in the hose where condensation or water can collect, as this can block airflow.
How many feet do you need for your run?
If you are replacing an entire run, I recommend adding 1 extra foot to your measurement to allow for trimming and a stress-free connection at the blower motor.
The Trident Marine 3" Blue Polyduct Blower Hose – 481-3000-FT is a reliable and cost-effective solution for maintaining proper ventilation and airflow on board.
