Sea-Dog Hose Thru Vent, 4 Inch, White

The Sea-Dog Hose Thru Vent (337415) is a white, injection molded ABS vent fitting designed for cabin or bilge ventilation aboard boats. It is built for use with 3 inch or 4 inch exhaust hose, letting you route ventilation ducting through a bulkhead, deck, or hull surface to promote airflow and reduce moisture and odor buildup in enclosed spaces. The vent features a molded flange design with an overall diameter of 4-15/16 inches and a hose/hole size of 4 inches, providing 4.05 square inches of open vent area for effective air exchange.

Construction is UV resistant injection molded ABS, chosen to withstand sun exposure and marine conditions over time. The vent should not be allowed to contact acetone or other strong solvents, which can damage the ABS material. Installation is straightforward: the vent mounts with four #8 flat head fasteners (not included), making it a simple add-on or replacement for cabin, engine compartment, or bilge ventilation systems. This vent is finished in white; the same style is also offered in black under a separate part number for buyers who need to match different interior or hull colors.
