The MOELLER 03380710 Brass Anti-Siphon Valve is designed for dependable fuel-system connection and flow control in marine and other compatible applications. Featuring a durable brass body, this valve combines a barbed hose connection with a female NPT threaded port to support a secure, serviceable installation. Its compact inline design is well suited for use where reliable fuel delivery and protection against siphoning are important considerations.
The brass construction provides strength and corrosion resistance for demanding service environments, including applications exposed to fuel, vibration, and changing temperatures. The hose barb is intended to provide a firm connection when paired with the appropriate fuel-rated hose and properly secured clamp. The threaded port should be installed with a compatible sealant or sealing method approved for the specific fuel-system application, while care should be taken to avoid overtightening during installation.
