Discover our highly polished Silicone 4" Bronze Vent, featuring a durable, high-gloss powder-coated interior. Standardized in Red, this vent seamlessly threads into the deck plate with 12 treads per inch, ensuring both functionality and elegance for your vessel. Crafted through traditional sand casting techniques, our vents boast a distinctive, traditional appearance. While certain areas may exhibit a slightly rough texture, particularly on the interior where polishing is challenging, the exterior boasts a highly polished, smooth surface with a mirror finish. Our bronze vents undergo meticulous polishing and buffing processes, without any additional coatings applied, allowing them to naturally develop a beautiful patina over time, enhancing their timeless allure.
