About Reliable Safety and Flow Corporation

Bringing together more than 175 years of innovation, quality, and customer commitment under one name and one promise.

The company was forged in 1850, as American industry was being connected by pipe, valves, fittings, and the skilled people who knew how to put them in the right place. More than 175 years later, that heritage lives in ASC Engineered Solutions, a comprehensive pipe preparation, joining, hanging and flow‑management portfolio supporting the people who build and maintain commercial buildings, industrial facilities, infrastructure, and critical systems. A house of brands, Anvil, Gruvlok, Sharpe, SCI, and ABZ, unified as ASC in 2019, and the portfolio has grown in the years since.

In 1920, Reliable Automatic Sprinkler started doing one thing exceptionally well: building the fire safety systems that protect people and property. Sprinklers, valves, and accessories, made in the United States. More than a century later, the discipline has not changed. A century of American‑made fire protection products, with multi‑generational customer relationships and multi‑decade specifications. A century of protecting what matters the most.
