Vertical Dry Snorkel Brownie’s Vertical Dry Snorkel stands high and proud at a safe distance above the water line and away from the engine exhaust protecting the compressor and your health. The Dry Snorkel is tight-tolerance crafted in our own machine shop from Delrin round stock to a perfect press-together seal so that no adhesives or glue are used in this critical component. The large bore tube of the main snorkel is considerably larger than required for airflow, but structurally doubles as the main support for our stainless reinforced custom sewn dive flag.
