This is a pencil-style engine anode with brass plug. Zinc is intended for saltwater use.\u003c\/p\u003e\n\u003cp data-start=\"417\" data-end=\"431\"\u003eKey Features\u003c\/p\u003e\n\u003cul data-start=\"432\" data-end=\"620\"\u003e\n\u003cli data-start=\"432\" data-end=\"469\"\u003eZinc pencil anode with brass plug\u003c\/li\u003e\n\u003cli data-start=\"470\" data-end=\"495\"\u003eThread size: 3\/8\" NPT\u003c\/li\u003e\n\u003cli data-start=\"496\" data-end=\"520\"\u003eAnode diameter: 1\/2\"\u003c\/li\u003e\n\u003cli data-start=\"521\" data-end=\"541\"\u003eAnode length: 2\"\u003c\/li\u003e\n\u003cli data-start=\"542\" data-end=\"620\"\u003eDesigned for engine cooling system and heat exchanger corrosion protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"622\" data-end=\"946\"\u003eEngine Compatibility\u003cbr data-start=\"642\" data-end=\"645\"\u003eThis part is used across a range of marine engines, generators, coolers, and heat exchanger systems that take a 3\/8\" NPT pencil anode in the 1\/2\" x 2\" size. Fitment should be confirmed by thread size, anode length, anode diameter, and the installed plug\/anode style rather than by engine family alone.\u003c\/p\u003e\n\u003cp data-start=\"948\" data-end=\"1201\"\u003eSerial Number Fitment Notice\u003cbr data-start=\"976\" data-end=\"979\"\u003eFitment should be confirmed by cooling-system anode size and thread specification rather than serial number alone. Match the existing anode by 3\/8\" NPT plug thread, 1\/2\" anode diameter, and 2\" anode length before ordering.\u003c\/p\u003e\n\u003cp data-start=\"1203\" data-end=\"1511\"\u003eWhen This Part Needs Replacement\u003cbr data-start=\"1235\" data-end=\"1238\"\u003eReplace 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.\u003c\/p\u003e\n\u003cp data-start=\"1513\" data-end=\"1906\"\u003eInstallation Notes\u003cbr data-start=\"1531\" data-end=\"1534\"\u003eInstall only where a 3\/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 does not interfere with the internal passage. Zinc is the correct material for saltwater applications; for other water conditions, material choice should be confirmed by application.\u003c\/p\u003e\n\u003cp data-start=\"1908\" data-end=\"1945\"\u003eAlternate \/ Superseded Part Numbers\u003c\/p\u003e\n\u003cul data-start=\"1946\" data-end=\"1973\"\u003e\n\u003cli data-start=\"1946\" data-end=\"1954\"\u003eCME1\u003c\/li\u003e\n\u003cli data-start=\"1955\" data-end=\"1962\"\u003eE-1\u003c\/li\u003e\n\u003cli data-start=\"1963\" data-end=\"1973\"\u003eCMT-E1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1975\" data-end=\"2268\"\u003eParts Desk Insight\u003cbr data-start=\"1993\" data-end=\"1996\"\u003ePencil anodes are one of the simplest and most important maintenance items in raw-water cooling systems. Matching the thread is only part of the job—the anode diameter and length also need to match the housing so protection is correct and internal clearance is maintained.\u003c\/p\u003e\n\u003cp data-start=\"2270\" data-end=\"2346\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eShipping\u003cbr data-start=\"2278\" data-end=\"2281\"\u003eShipping: Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564132532260,"sku":"CMT-E1","price":11.56,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/6f89454e-9a01-4c57-b57a-da7092111ea5.png?v=1775440414","url":"https:\/\/marisolmarine.com\/products\/zinc-pencil-anode-3-8-npt-cmt-e1","provider":"Marisol Marine Company","version":"1.0","type":"link"}
