Description
Aeroflow Sacrificial Zinc Anode 1/4″ NPT Cooling System Plug
Safeguard your high-performance cooling system against electrolytic action and stray current damage with Aeroflow’s premium sacrificial zinc anode plug.
Overview & Protection Benefits
Galvanic corrosion and stray electrical currents within performance cooling loops can rapidly cause pitting, erosion, and premature failure of aluminum radiators, intake manifolds, and cylinder heads. The Aeroflow AF49-2500 Sacrificial Zinc Anode Plug provides vital protection by attracting stray voltage and electrolytic reactions away from your alloy components.
Designed with a standard male 1/4″ NPT thread, this plug easily threads into radiator ports, water necks, or custom expansion tanks. As coolant circulates, the sacrificial zinc element degrades over time instead of your expensive engine and cooling hardware, preserving system integrity in demanding race and street applications.
Key Features
- ☑ Electrolysis Prevention: High-purity zinc element sacrificially corrodes to protect alloy components.
- ☑ Standard Thread Pitch: 1/4″ NPT male thread fits directly into common cooling system ports.
- ☑ Durable Brass Body: Precision-machined hex plug ensures a secure, leak-free seal.
- ☑ Universal Compatibility: Perfect for alloy radiators, custom header tanks, and motorsport cooling circuits.
- ☑ Essential Maintenance Item: Easily replaceable during routine cooling system service.
