<h3>About Flow-Rite Controls</h3><p>Since 1981, <strong>Flow-Rite Controls</strong> has built a reputation as one of the most trusted names in fluid control technology for the marine, battery care, and hydroponics industries. Founded in Michigan by Dan Campau, the company has grown from a focused engineering startup into a vertically integrated manufacturer with a global footprint — while keeping its roots, and its production, firmly in the USA.</p><p>What sets Flow-Rite apart is its commitment to owning the entire product lifecycle. From cutting-edge research and development to injection-molded tooling, assembly, and logistics, every step happens under one roof. This end-to-end control is what allows Flow-Rite to maintain an exceptional on-time delivery record and the kind of consistent quality that has made it a preferred partner for top OEM boat builders across the country.</p><h3>Marine Plumbing &amp; Livewell Systems</h3><p>Flow-Rite is best known in the boating world for its innovative marine plumbing systems, valves, and fluid control devices. The brand&apos;s patented <strong>Qwik-Lok&reg;</strong> quick-connect fittings have become an industry standard, offering boaters and boat builders a fast, reliable alternative to traditional barb-style hose connections. Whether you&apos;re managing ballast systems on a wakeboard boat or keeping a livewell fully oxygenated on a bass boat, Flow-Rite has engineered a solution to meet the need.</p><p>The <strong>PowerJet Plus Aerator</strong> exemplifies the brand&apos;s approach to innovation — using a high-pressure water jet to infuse livewells and baitwells with oxygen, dramatically improving the survival rate of live bait and catch. Trusted by tournament anglers and recreational fishermen alike, these systems reflect Flow-Rite&apos;s deep understanding of on-the-water performance demands. Their thru-hull fittings combine polished 316L stainless steel flanges with glass-filled composite polymer bodies, and are ABYC &amp; NMMA compliant for above-waterline applications.</p><h3>Battery Care &amp; Watering Systems</h3><p>Beyond the water, Flow-Rite is equally respected in the battery maintenance space. The brand&apos;s battery watering systems — including the <strong>Pro-Fill</strong> and <strong>Millennium</strong> series — help industrial, marine, and RV users extend the life of their deep-cycle lead-acid batteries by simplifying the watering process and reducing the risk of over- or under-watering. These systems are engineered with the same precision and durability that define all Flow-Rite products.</p><h3>American-Made, Patent-Protected Innovation</h3><p>Every Flow-Rite product is a proprietary development, backed by dozens of U.S. patents and hundreds of international patents. The company holds ISO 9001 certification, reflecting its rigorous commitment to quality management and continuous improvement. Whether you&apos;re a professional boat builder, a tournament angler, or a fleet maintenance manager, Flow-Rite&apos;s lineup of fluid control products delivers the reliability and innovation that demanding applications require.</p>
