SS 304L UNION SMS CNC ELECTRO POLISHED

The Stainless Steel 304L SMS Union, CNC machined and electropolished, is a precision-engineered hygienic fitting designed for secure, leak-proof connections in sanitary piping systems. Commonly used in the food, beverage, dairy, pharmaceutical, and biotechnology industries, this union provides easy assembly, disassembly, and maintenance in critical process environments.

Manufactured from AISI 304L stainless steel, the fitting offers excellent corrosion resistance, enhanced weldability, and compatibility with a wide range of process fluids. The CNC machining ensures precise tolerances, optimal surface alignment, and consistent quality, while the electropolished internal surface (Ra ≤ 0.8 μm) delivers a smooth, bright finish that improves cleanability and minimizes bacterial adhesion—essential for hygienic applications.

The SMS (Swedish Manufacturing Standard) design consists of three main components: a liner, male part, and hex nut, along with a gasket. This standard is widely recognized in sanitary applications across Europe and internationally.
