Marshall Excelsior Co.

<h3>About Marshall Excelsior Company (MEC)</h3><p><strong>Marshall Excelsior Company (MEC)</strong>, headquartered in Marshall, Michigan, is a precision manufacturer of world-class LPG and NH3 (Anhydrous Ammonia) equipment. For over half a century, MEC has been at the forefront of gas control innovation, engineering reliable solutions for Bulk Plant, Transport, Delivery/Dispensing, and Domestic and Recreational applications worldwide.</p><p>MEC's roots trace back to the manufacture of brass fittings and copper pigtails — the foundational product lines that launched the company. Over the decades, those humble beginnings evolved into a comprehensive portfolio of liquid and gas valve solutions, pressure relief devices, pressure regulating control valves, and a full range of accompanying equipment. Today, MEC is widely recognized as one of the industry's most trusted names in gas-handling technology, with proprietary product lines such as the Excela-Flo&trade; regulators, Excela-Flange&trade; truck and plant equipment, Excelerator&trade; internal valves, Turbo-Flo low-emission equipment, and Accu-Max&trade; float gauges — each engineered to meet demanding operational requirements.</p><p>Quality is central to everything MEC produces. Every product is manufactured under rigorous standards, and MEC backs its equipment with a 5-year warranty alongside an impressive 25-year regulator service life — a testament to the durability built into each component. The company also operates the industry's first LPG flow test laboratory at its Marshall, Michigan headquarters, where products are validated using actual liquid propane rather than water or air, ensuring real-world performance before any product ever reaches the field.</p><p>In 2024, MEC was acquired by <strong>OPW Global</strong>, a division of Dover Corporation (NYSE: DOV), further reinforcing its financial backing and global reach. The acquisition positioned MEC within Dover's Clean Energy &amp; Fueling segment, expanding its ability to serve customers across international markets while maintaining the engineering excellence and customer-first approach that built its reputation.</p><p>MEC's transport and heavy-equipment heritage makes it a natural fit for demanding vehicle and fleet applications. Their precision-engineered <a href="/7451-marshall-excelsior-co-hvac-heater-control-valve-6860">HVAC heater control valves</a> deliver the tight tolerances and reliable gas-flow regulation that heating systems depend on — especially in commercial and fleet vehicles operating in harsh conditions. Equally important to transport operators, MEC's <a href="/7451-marshall-excelsior-co-air-brake-fitting-17275">air brake fittings</a> reflect the same commitment to safety and durability that has defined the brand since its earliest days manufacturing brass fittings for the LPG industry.</p><p>Whether you are maintaining a propane delivery fleet, equipping a bulk plant, or sourcing precision fittings for heavy-duty transport vehicles, Marshall Excelsior Company delivers engineered solutions backed by decades of innovation, rigorous testing, and a global support network.</p>

  • 1/4 inch MNPT fitting compatible with standard low-pressure regulators
  • 7/8 inch hex nut for easy installation and removal

Purchased a CTEK 7002 battery tender because of how great they work for keeping all the toys charged up over the cold months. Autoplicity had, by far the best price on this product. Couldn't ask for more.
