Additional Information

High-Quality Brass Anti-Siphon Valve for Marine Fuel Systems

Marine safety starts with reliable fuel management components. The EVM A/S 162-B is a premium brass anti-siphon valve designed for durability. This specific model features 1/4" MNPT by 1/4" MNPT threading. It is a critical safety component for any gasoline-powered vessel. Because fuel leaks pose a significant fire risk, a functional valve is mandatory. This valve ensures that fuel only flows when your engine is running. Therefore, it protects both your boat and your passengers during every trip.

Essential Protection Against Fuel Siphoning

The primary role of this valve is to prevent gravity siphoning. If a fuel line breaks or leaks, fuel could drain into the bilge. This creates a highly dangerous and flammable environment. However, the EVM 160 series utilizes a spring-loaded check ball. This ball stays seated until the fuel pump creates suction. As a result, fuel remains safely inside the tank when the engine is off. This simple mechanism provides essential peace of mind for boat owners.

Durable Brass Construction for Marine Environments

Corrosion is a constant threat in marine settings. This valve is constructed from high-grade brass to resist the elements. Brass offers superior strength and longevity compared to standard materials. Additionally, it handles the vibrations of a marine engine without failing. The 1/4" MNPT connections provide a secure and airtight fit. Consequently, you can trust this fitting for long-term performance. It meets strict safety standards to ensure your vessel remains compliant.

Simple Installation and Reliable Performance

Replacing an old valve is a straightforward maintenance task. You can easily thread this 162-B model into your fuel tank pickup. It is designed for universal compatibility with 1/4" NPT fuel systems. Furthermore, using original EVM parts ensures a perfect fit every time. If you notice a drop in fuel pressure, your old valve may be clogged. Swapping it for a new brass unit restores efficiency quickly. Macomb Marine Parts provides the authentic components you need for a professional repair.
