Description

The Moeller 033807-10 is a brass anti-siphon valve designed for marine fuel systems. It features a straight fitting with a 3/8-inch hose barb on one end and 1/4-inch Male NPT threads on the other. This valve provides anti-siphon protection, which is required by federal law for permanent fuel tank installations where the hose dips below the top of the tank.
