After years of rigorous testing, the Naval Sea Systems Command (NAVSEA) has approved the use of MegaPress CuNi mechanically attached fittings in sizes 1/2-inches to 2-inches in surface combatants for a variety of systems, including chilled water, potable water, electronic freshwater cooling, seawater cooling, washdown countermeasures, drainage and many others.
