Additional Information

Upgrade Your Fuel System with the Aluminum Anti-Siphon Valve

Maintaining a safe vessel requires reliable fuel system components. The Aluminum Anti-Siphon Valve 3/8" MNPTF x 1/2" Barb is an essential safety device. Specifically, the EVM A/S L-170-1/2 model prevents fuel from siphoning into the bilge. This protection is vital if a fuel line happens to break. Consequently, it significantly reduces the risk of fire or environmental damage.

Durable Construction and Precise Engineering

This valve features a rugged aluminum body. Aluminum offers excellent resistance to the harsh marine environment. Moreover, it provides a lightweight yet durable solution for your boat. The 3/8" MNPTF connection ensures a secure fit into your fuel tank. Meanwhile, the 1/2" barb side allows for a tight seal with your fuel hose. Therefore, you can trust this component for long-term performance.

Why Anti-Siphon Protection Matters

Safety regulations often require these valves on marine engines. They function by remaining closed unless the engine creates a vacuum. This means fuel only flows when the engine is actually running. If a leak occurs downstream, the valve stays shut. As a result, your boat remains protected from dangerous fuel pooling. Investing in a quality EVM Inc. valve is a smart move for every boat owner.

Easy Installation and Compatibility

The EVM A/S L-170-1/2 is designed for simple integration. It fits standard marine fuel systems with ease. Because of its precise threading, you can install it quickly. However, always ensure your hose sizes match the 1/2" barb. Proper installation ensures the valve operates correctly under pressure. Additionally, using high-quality aluminum parts prevents premature corrosion.

Is aluminum better than brass for fuel valves? Aluminum is highly resistant to corrosion in many marine environments and is lighter. Both materials are common, but aluminum is often preferred for specific fuel tank setups.

What are the thread and barb sizes for this model? This specific model features a 3/8" MNPTF (Male National Pipe Thread Fine) inlet and a 1/2" hose barb outlet.

Does this valve meet Coast Guard requirements? Yes, EVM Inc. manufactures these valves to meet standard marine safety regulations regarding fuel system protection.

How often should I replace my anti-siphon valve? You should inspect the valve annually for clogs or corrosion. Replace it if the internal spring sticks or if you notice any restricted fuel flow to the engine.
