Sea-Dog Hose Thru Vent 3 Inch, White, UV Resistant ABS Cabin and Bilge Vent

The Sea-Dog Hose Thru Vent (337315) is a white, injection molded ABS vent fitting designed for cabin or bilge ventilation aboard boats. It is sized for use with 3 inch exhaust hose, making it a straightforward way to route fresh air into an enclosed compartment while keeping moisture and debris out. The vent body is constructed of UV resistant ABS, so it holds up to sun exposure without becoming brittle or discolored over time, and it should be kept away from acetone or other strong solvents that can degrade the plastic.

Installation is simple: the vent mounts with four #8 flat head fasteners (not included), and its compact overall footprint of 3-11/16 inches keeps the surface profile low on cabin walls, lockers, or bilge compartments. With a vent area of 3.04 square inches, it provides ample airflow for hose-fed ventilation runs. The Sea-Dog Hose Thru Vent is sold in white and is also offered in a black finish and in a 4 inch hose size as separate part numbers, so buyers should confirm color and hose size before ordering.
