Sea-Dog Flush Thru Vent 337416-1, White ABS, Fits Up to 4 Inch Hose

The Sea-Dog Flush Thru Vent (part number 337416-1) is a white, injection molded ABS vent designed for cabin or bilge ventilation aboard a boat. It is sized for use with hose up to 4 inches in diameter, making it suited for routing ventilation air through a cabin bulkhead, deck, or bilge compartment wall. The vent provides 4.05 square inches of net free ventilation area, allowing air to pass through while the flush profile keeps the fitting low and unobtrusive on the mounting surface.

Construction is UV resistant injection molded ABS, chosen for its resistance to sun exposure and general durability in a marine environment. The vent should not be allowed to contact acetone or other strong solvents, which can damage the ABS material. Installation is straightforward, using four number 8 flat head fasteners (fasteners are not included and must be purchased separately). Beyond exhaust and bilge ventilation duty, this style of vent is also commonly used for general ventilation applications such as stairway, deck, or patio downlight housings. This vent does not include an insect screen.
