Scepter

<h3>Scepter: Over 70 Years as the King of Containers</h3><p>Since 1949, Scepter has earned its reputation as one of the world's foremost manufacturers of fuel and water containers. What began as a pioneer in container design has evolved into a global trailblazer, serving consumers, marine enthusiasts, and military operators across the globe. <strong>Few brands can claim seven decades of continuous innovation</strong> in a single product category — Scepter is one of them.</p><p>Scepter's product philosophy centers on three pillars: safety, durability, and ease of use. As a sponsor of the National Gasoline Safety Project, the company takes fuel-handling compliance seriously, engineering every container to meet or exceed EPA and CARB standards. Whether you're fueling a lawn mower, powering an outboard motor on the open water, or supplying a forward operating base, Scepter builds containers that work reliably under demanding real-world conditions.</p><h3>Marine Fuel Tanks Built for Life on the Water</h3><p>Among Scepter's most trusted product lines are its <a href="/12820-scepter-portabletopside-tanks-202368">portable and topside marine fuel tanks</a> — engineered specifically for boaters who demand performance and safety in equal measure. These tanks are constructed from rugged, crush-resistant, UV-stabilized high-density polyethylene (HDPE), featuring seamless one-piece shells that resist corrosion, rust, and vapor evaporation. Scepter's signature 2-way vented cap automatically releases pressure above 5 PSI to prevent dangerous vapor buildup, while a built-in fuel gauge lets boaters check levels at a glance without removing the cap.</p><p>For smaller outboard-powered vessels and pontoon boats, Scepter also offers a range of <a href="/12820-scepter-portabletopside-tanks-200799">compact portable and topside tanks</a> that fit neatly under seats or in tight deck compartments. Capacities ranging from 3 to 12 gallons give boaters the flexibility to match their tank to their vessel's needs, while compatibility with standard 1/4 NPT marine fittings ensures seamless integration with virtually any outboard engine setup.</p><h3>A Complete Ecosystem of Fuel Handling Products</h3><p>Beyond fuel tanks, Scepter's catalog extends to consumer jerry cans, SmartControl gasoline and diesel containers with precision-flow spouts, wheeled fuel caddies, and a full suite of marine accessories — from inline fuel filters and motor flushers to hose menders and fluid transfer pumps. This breadth of offerings makes Scepter a one-stop resource for safe fuel storage and dispensing across virtually every outdoor and marine application.</p><p>As a publicly traded company operating under Myers Industries, Scepter combines the agility of a specialized manufacturer with the resources of a larger organization, continuously investing in new materials, compliance testing, and product innovation. For anyone who handles fuel regularly — on the water, in the yard, or in the field — Scepter's lineup represents a benchmark for quality and safety that has stood the test of time.</p>
