Camp Zinc

<h3>About Camp Zinc (Camp Company)</h3><p><strong>Camp Zinc</strong>, the consumer-facing brand of Camp Company, is a leading manufacturer of marine anodes. Their zinc and aluminum sacrificial anodes are manufactured in the US to ensure the highest quality of corrosion protection. For boaters, that American-made heritage matters — it means consistent alloy quality, tighter tolerances, and confidence that every anode performs as advertised when your boat hits the water.</p><h3>What Are Sacrificial Anodes and Why Do They Matter?</h3><p>Galvanic corrosion is one of the most damaging and insidious threats to any vessel. Cathodic protection is one of the most effective methods of preventing galvanic corrosion on underwater metal constructions and in heat exchangers, and sacrificial anodes are the main components of this kind of protection — though they have to be replaced regularly for best effect. In simple terms, a sacrificial anode is a less-noble metal (zinc or aluminum) that corrodes in place of your expensive underwater hardware, sparing your propeller shafts, rudders, and drive components from damage.</p><h3>A Full Range of Marine Anode Solutions</h3><p>Camp Company anodes are manufactured for use on recreational, commercial, and military vessels, placed on hulls, propeller shafts, rudders, trim tabs, outboard engines, stern drives, and in the cooling system of most inboard engines to protect metal parts from galvanic corrosion. That breadth of coverage is a hallmark of the brand — whether you run a small outboard skiff or a large commercial workboat, Camp Zinc has a purpose-built anode solution.</p><p>At the heart of Camp Zinc&apos;s lineup are their <a href="/7286-camp-zinc-anode-kits-201633">Anode Kits</a>, which bundle together all the anodes needed to fully protect a specific engine or drive system. Rather than sourcing individual pieces, boaters can grab a kit and know their entire drivetrain is covered. Camp also offers a second, complementary line of <a href="/7286-camp-zinc-anode-kits-200102">Anode Kits</a> tailored to a different range of outboard and sterndrive applications, making it easy to find the right match for your specific make and model.</p><p>For boaters who need ancillary hardware to complete their anode installations, Camp Zinc also supplies <a href="/7286-camp-zinc-tie-strap-and-clip-10142">Tie Straps and Clips</a> — the small but essential fastening components that secure anodes and associated wiring properly to the vessel.</p><h3>MIL-SPEC Standards You Can Trust</h3><p>Camp Company is one of the leading American enterprises specializing in manufacturing aluminum and zinc marine anodes, and the company makes its products compliant with high standards and special military specifications peculiar to this kind of goods. Marine anodes conform to MIL-SPEC standards, including Mil-A-18001 for zinc anodes. These standards ensure that every anode has the proper electrochemical potential to protect your boat&apos;s metal components — no guesswork, no shortcuts.</p><p>Whether you&apos;re maintaining a Yamaha outboard, a Volvo Penta sterndrive, a Mercury drive, or a commercial inboard, Camp Zinc delivers the corrosion protection professionals and passionate boaters alike have depended on for years.</p>

Product Details

The Camp Zinc R4 is a two-piece, pancake-style zinc anode designed for protecting rudders and trim tabs from galvanic corrosion in saltwater marine environments. This professional-grade sacrificial anode features a stainless steel nut pressed into one piece, with a stainless steel socket cap screw (allen head) connecting the two halves together.

Key Features:

  • 5-inch diameter design with 1-1/2" fastener
  • Military-grade zinc construction meeting US MIL-SPEC standards
  • Formulated specifically for saltwater use
  • Two-piece clamping design for easy installation on rudders and trim tabs
  • Stainless steel hardware for reliable, long-lasting performance
  • Brass bushing included for permanent electrical ground

Sacrificial zinc anodes are essential for protecting underwater metal components on boats. The Camp Zinc R4 provides reliable galvanic corrosion protection by corroding preferentially to more valuable metals like bronze, stainless steel, and aluminum. This anode should be inspected regularly and replaced when 50% depleted to maintain optimal protection.
