It is the standard material for marine fittings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cspan class=\"faq-question\"\u003eCan I use this vent on my boat's fuel tank?\u003c\/span\u003e\n\u003cp class=\"faq-answer\"\u003eYes. This is designed for both fuel and fresh water tanks. It allows fuel vapors to vent safely and prevents a vacuum from forming, which can deform a fuel tank, ensuring smooth fuel flow to your engine.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cspan class=\"faq-question\"\u003eAre the rubber gasket and lock nut included with the purchase?\u003c\/span\u003e\n\u003cp class=\"faq-answer\"\u003eAbsolutely. Just like in our photos, every order includes the stainless steel vent head assembled with the threaded body, the rubber sealing washer for a water-tight fit against the hull, and the locking nut. You won't need to buy extra hardware.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cspan class=\"faq-question\"\u003eHow do I know which size vent to buy?\u003c\/span\u003e\n\u003cp class=\"faq-answer\"\u003eMeasure the hole you have in your boat's hull or your existing pipe. For 1-inch and 1-1\/4 inch hoses, choose the smaller model with the 33mm thread OD. For 1-1\/2 inch and 2 inch hoses, choose the larger model with the 48mm thread OD. If you are unsure, it is always best to measure the existing tank vent thread diameter first.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cspan class=\"faq-question\"\u003eIs the top vent screen removable to be cleaned?\u003c\/span\u003e\n\u003cp class=\"faq-answer\"\u003eThe top head is designed as a secure unit to prevent tampering, but the slotted gaps are wide enough to let air pass while catching major debris.
