Sea-Dog Hose Thru Vent 337325, 3 Inch Black ABS Cabin and Bilge Vent

The Sea-Dog Hose Thru Vent (337325) is an injection molded ABS vent fitting designed for cabin or bilge ventilation aboard boats. It is built to accept 3 inch exhaust hose, with a hose/hole size of 3 inch to 3-1/8 inch, making it a practical solution for routing fresh air into enclosed spaces below deck. The vent is constructed of UV resistant ABS plastic, which helps it withstand sun exposure and marine conditions without becoming brittle or discolored over time.

This vent features an open face design with 3.04 square inches of vent area, allowing airflow to pass through while the housing protects the hose connection point. It mounts using four number 8 flat head fasteners, which are not included and must be purchased separately. The unit is finished in black to blend with dark-colored hull and deck surfaces, and Sea-Dog also offers a white version and larger 4 inch versions for different hose sizes. Builders and installers requiring custom colors can inquire about large volume orders. Users should avoid exposing this vent to acetone or other strong solvents, as these can damage the ABS material.

Compact and lightweight, the Sea-Dog Hose Thru Vent is a straightforward, functional component for boat owners upgrading or repairing bilge and cabin ventilation systems.
