Federal law requires anti-siphon protection on permanent fuel tank installations if the hose dips below the top of the tank, and this valve is designed to meet that requirement while providing a secure connection point between the fuel line and the tank fitting. It features a 3\/8 inch hose barb outlet paired with a 3\/8 inch NPT (National Pipe Tapered) threaded inlet, giving installers a threaded connection on one side and a barbed hose connection on the other.\u003c\/p\u003e\u003cp\u003eThis valve carries a 15 Calibration, which yields 15 inches of vertical height protection and is intended for use on engines rated 200 horsepower and above. It is constructed of brass with a brass exterior finish, has 2 ports, and is rated for a maximum operating pressure of 200 pounds per square inch. The valve meets ABYC H-24 specification. It is a straightforward, drop-in style component for boat builders and repair technicians installing or replacing anti-siphon protection on gasoline-powered boats with permanent fuel tanks.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
