Low Profile Cowl Vent PVC

Sea-Dog Low Profile Cowl Vent (part no. 727130-3) is a 3-inch diameter dip-molded PVC vent designed to provide cabin and bilge air intake with minimal deck protrusion. Its 4-1/4-inch installed height reduces the chance of fouling lines or restricting crew movement while delivering steady ventilation.

When taller vents interfere with deck gear or crew access, this low profile design offers a direct solution. Use it with a dorade box for intake ventilation or alone for bilge ventilation with or without a blower. The vent includes a snap-on deck plate and a cover to protect the inlet in rough weather.

• 3 in diameter body fits a required 3-3/4 in hole
• Installed height 4-1/4 in for low deck clearance
• Dip-molded UV-resistant PVC construction resists sun degradation
• Snap-on deck plate and removable cover for rough conditions
• Available with red interior for visibility and easier alignment

Compared to taller cowl vents this unit reduces snag points near lifelines, winches, and handholds. Unlike some metal vents it uses PVC to avoid common galvanic concerns and to remain lightweight. It is suitable for sailboats and workboats where deck clearance and simple installation are priorities.

Manufacturer Sea-Dog specifies part number 727130-3 and warns to avoid contact with acetone or strong solvents. Verify your deck thickness and the 3-3/4 in hole size before installation to ensure a proper fit for your vessel.
