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>

NICE

Autoplicity has the best prices around! They were quick to email a confirmation of the order, shipment, and delivery. I was VERY impressed! I also received my order earlier than I thought, which is always a plus. Will definitely do business with them again! Thanks!

i ordered a b&w companion hitch on Monday and it was sitting at my house on Friday. Exactly what i ordered and when i needed it. Will definately order from them again.

easy and fast

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.
