Moeller Anti-Siphon Valve Fuel Hose Fitting, 3/8 in. Barb x 3/8 in. NPT, Aluminum, 30 Calibration (033802-10)

The Moeller 033802-10 is an aluminum anti-siphon valve fitting that combines anti-siphon protection with a hose barb connection in a single fuel-line component. It is built with a 3/8 inch hose barb on one end and a 3/8 inch NPT threaded connection on the other, allowing it to join a fuel hose directly to a threaded fuel tank fitting while providing the anti-siphon function required for certain permanent fuel tank installations. The valve carries a 30 calibration rating.

Federal law requires anti-siphon protection on permanent fuel tank installations where the fuel hose dips below the top of the tank, and this fitting is designed to satisfy that requirement while keeping the fuel line connection simple and leak-resistant. The aluminum body gives it a durable, corrosion-resistant construction suited to the marine fuel system environment, and the silver aluminum finish matches typical fuel system hardware. It is a single-piece fitting (one unit per package) intended for use in boat fuel line and fuel tank plumbing where a barb-to-NPT anti-siphon connection is needed.
