Manufacturers Standardization Society (MSS) is a globally recognized leader in developing technical standards for valves, fittings, flanges, and piping systems. Founded in 1924 by 38 manufacturers, MSS traces its roots to 1908 when the Valve and Fittings Institute formed a standardization committee. The organization published its first Standard Practice (SP-1) for pipe plugs in 1929, establishing its enduring legacy in industrial standardization. Today, MSS facilitates consensus-driven standards that ensure safety, reliability, and interoperability across fluid control systems. Serving manufacturers, engineers, and regulators, MSS continues to advance best practices for piping components through collaborative industry expertise and innovation.
