A compact tank vent fitting for 5/8"hose. Tank vents allow air in and out of the tank as tank levels and temperatures change. This is especially important to prevent blow-back while filling a tank or vacuum build-up when drawing from the tank. Our thru-hull vents provide a compact solution to tank ventilation. These chrome plated brass fittings feature two screened openings that can be clocked to prevent unwanted contaminates from entering the tank. An integrated hose barb provides a secure connection for the vent hose.
