Zinc OMC Waffle Bar Anode CMT-367Z

Martyr CMT-E00 is a zinc pencil anode sized 1/8″ NPT x 1/4″ x 2″, designed to help protect marine engine cooling passages, heat exchangers, oil coolers, and other internal raw-water components from galvanic corrosion in saltwater service. This is a pencil-style anode used in applications that require the exact 1/8″ NPT thread with a 1/4″ diameter and 2″ anode length. Zinc is intended for saltwater use.

Key Features

• Zinc pencil anode
• Thread size: 1/8″ NPT
• Anode diameter: 1/4″
• Anode length: 2″
• Designed for internal raw-water cooling system corrosion protection
• Size-specific replacement for applications using this exact pencil anode format

Engine Compatibility
This part is used across a range of marine engines, generators, coolers, and heat exchanger systems that take a 1/8″ NPT pencil anode in the 1/4″ x 2″ size. Fitment should be confirmed by thread size, anode diameter, anode length, and installed housing style rather than by engine family alone.

Serial Number Fitment Notice
Fitment should be confirmed by cooling-system anode size and thread specification rather than serial number alone. Match the existing anode by 1/8″ NPT plug thread, 1/4″ anode diameter, and 2″ anode length before ordering.

When This Part Needs Replacement
Replace when the zinc is heavily wasted, brittle, scaled, reduced in diameter, or no longer providing usable protective mass. Pencil anodes should be inspected regularly because they protect internal cooling passages where corrosion can become costly if service is delayed.

Installation Notes
Install only where a 1/8″ NPT pencil anode of this exact size is specified. Remove the old anode carefully, inspect the plug threads and sealing surfaces, and confirm the replacement length and diameter match the housing correctly. Zinc is the correct material for saltwater applications.

Parts Desk Insight
With pencil anodes, matching the thread alone is not enough. Diameter and overall length also need to match the housing correctly so the anode protects properly without creating clearance issues inside the cooler or water passage.
