It is built for use with 3 inch exhaust hose, allowing it to move air efficiently through the hull or bulkhead to help keep enclosed spaces dry and free of trapped moisture or fumes. The vent is constructed from investment cast 316 stainless steel, a corrosion resistant marine grade alloy chosen for its ability to withstand prolonged exposure to saltwater and marine air without rusting or pitting. Investment casting produces a dense, precisely formed part with a clean finish that holds up to years of outdoor exposure.\u003c\/p\u003e\u003cp\u003eInstallation is straightforward: the vent mounts with four #8 flat head fasteners (not included), so it can be fitted flush against the mounting surface for a low profile, finished appearance. The vent opening provides 3.04 square inches of open vent area, giving adequate airflow for its size. This is a compact fitting with an overall footprint of 2-7\/8 inches by 2-7\/8 inches and a 3-7\/8 inch overall dimension, making it suitable for tight mounting locations where a low-profile ventilation point is needed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 337590-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Flush Thru Vent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Investment Cast 316 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension A:\u003c\/strong\u003e 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension B:\u003c\/strong\u003e 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Dimension C:\u003c\/strong\u003e 3-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension D:\u003c\/strong\u003e 5\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose\/Hole Size:\u003c\/strong\u003e Up to 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Area:\u003c\/strong\u003e 3.04 square inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener:\u003c\/strong\u003e #8 flat head (not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.46 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Pack:\u003c\/strong\u003e 1 each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514338387\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sea-Dog 337590-1 used for?\u003c\/strong\u003e The Sea-Dog 337590-1 is a Flush Thru Vent used for cabin or bilge ventilation, allowing air to pass through a hull or bulkhead surface.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size hose does this vent work with?\u003c\/strong\u003e This vent is designed for use with 3 inch exhaust hose, per its Hose\/Hole Size rating of up to 3 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 337590-1 vent made of?\u003c\/strong\u003e It is made of investment cast 316 stainless steel, a corrosion resistant alloy suited to marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sea-Dog Flush Thru Vent corrosion resistant?\u003c\/strong\u003e Yes, the 316 stainless steel construction of the 337590-1 resists corrosion from saltwater and marine air exposure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the overall dimensions of the 337590-1 vent?\u003c\/strong\u003e The vent measures 2-7\/8 inches by 2-7\/8 inches, with a 3-7\/8 inch overall dimension and a 5\/16 inch dimension at D.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sea-Dog 337590-1 weigh?\u003c\/strong\u003e The 337590-1 Flush Thru Vent weighs 0.46 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the vent area of this fitting?\u003c\/strong\u003e The 337590-1 provides 3.04 square inches of vent area.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo fasteners come with the Sea-Dog Flush Thru Vent?\u003c\/strong\u003e No, fasteners are not included; the vent installs with four #8 flat head fasteners that must be purchased separately.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 337590-1 vent installed?\u003c\/strong\u003e It installs with four #8 flat head fasteners, mounting flush against the surface for a low-profile finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many #8 flat head fasteners are needed to install this vent?\u003c\/strong\u003e Four #8 flat head fasteners are required to install the Sea-Dog 337590-1 Flush Thru Vent.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this vent sold individually or in a pack?\u003c\/strong\u003e The Sea-Dog 337590-1 has a standard pack quantity of 1 each.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988755755227,"sku":"S-D-337590-1","price":28.21,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/8056.jpg?v=1784428909","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-flush-thru-vent-investment-cast-316-stainless-steel-3-hose-mpn-337590-1","provider":"Good Vibes Marina","version":"1.0","type":"link"}
