All Categories

Flange Adapter (ANSI)

The Flange Adapter (ANSI Flanges) is a specialized high-pressure fitting designed to transition securely between a fractional tube line and an ANSI-compliant flange interface. These adapters feature an integrally forged body and are available for tube sizes ranging from 1/4″ to 1″, supporting ANSI flange classes 150 and 300. Engineered for leak-proof reliability in industrial process systems, the fitting provides precise dimensions for length, orifice size, and hex flat configurations to ensure compatibility with standard ANSI B16.5 requirements.
