Engineered Marine Products 93-04804 E-2C Zinc Pencil Anode with Brass Plug 1/2" NPT

The Engineered Marine Products 93-04804 is an E-2C zinc pencil anode complete with brass plug, designed to provide reliable cathodic protection for marine engines. This sacrificial zinc anode installs directly into the engine block or heat exchanger via a 1/2" NPT threaded brass plug, where it gradually sacrifices itself to protect surrounding metal components from the damaging effects of galvanic corrosion in saltwater environments.

Key Features:

• Zinc Pencil Length: 1-5/8"
• Pencil Diameter: 5/8"
• Plug Thread Size: 1/2" NPT
• Wrench Size: 7/8"
• Material: High-purity zinc anode with brass plug
• Complete assembly — brass plug and zinc pencil anode included
• Zinc construction makes it ideal for saltwater and coastal marine environments
• E-2C series sizing for common marine engine applications

Regular inspection and replacement of pencil zinc anodes is an essential part of marine engine maintenance. If the anode is less than 50% of its original size, it should be replaced immediately to maintain effective corrosion protection and extend the life of critical engine components.
