CMP CME4 Zinc Pencil Anode with 3/4 NPT Plug for Marine Engine Cooling Systems

The CMP CME4 is a zinc pencil anode designed specifically for use in saltwater marine environments. Engineered to protect your engine's cooling system from galvanic corrosion, this sacrificial anode is an essential maintenance component for any saltwater vessel.

This pencil anode features a 3/4 inch NPT threaded plug, making installation straightforward in standard engine cooling system ports. The zinc construction provides reliable sacrificial protection, corroding in place of vital metal engine components to extend their service life.

Key Features:

• Material: Zinc — ideal sacrificial metal for saltwater applications
• Anode Dimensions: 3/4 inch outside diameter x 3-3/8 inch length
• Thread Size: 3/4 inch NPT plug included
• Application: Marine engine cooling system protection
• Environment: Saltwater use only
• Style: Pencil anode with integrated plug for easy drop-in replacement

Important: This anode is rated for saltwater use only. For freshwater or brackish water applications, an alternate anode material (such as magnesium) should be used. Regular inspection and replacement of pencil anodes is recommended as part of routine engine maintenance to ensure continuous corrosion protection.
