Sanitary Fittings

Match the fitting's nominal pipe size (inch or mm) and connection type (tri-clamp, BSP/NPT threads, butt weld) to your existing pipes or equipment; confirm sealing method (gasket, O-ring, buttweld) and measure inner diameter for flow-critical applications

Stainless steel 304 and 316 are common; 316 offers better corrosion resistance for high-salt or harsh chemical environments, while 304 is suitable for general food and beverage use; choose material based on chemical exposure, cleaning methods, and regulatory needs

Sanitary fittings designed with smooth internal finishes, crevice-free construction, and compatible materials (typically 304/316 stainless steel) are intended for hygienic applications; confirm surface finish (e.g., #3, #4 polish) and compliance with industry standards for your specific process

Regular inspection for scratches, pitting, and gasket wear; clean with approved detergents and CIP/SIP procedures compatible with the fitting material; replace gaskets and O-rings periodically and avoid abrasive tools that damage finishes

Check standardized dimensions (ID/OD, flange spacing), connection standards (ISO, DIN, ASME, BS), and gasket profiles; if dimensions and standards match, fittings from different manufacturers are typically interoperable

Look for maximum working pressure and temperature ratings, surface finish (Ra value or polish grade), and any certification notes; ensure ratings exceed your process's operating conditions with a safety margin

Expect a range from lower-cost basic fittings under $50 to higher-grade or specialty stainless fittings above that; factor in gaskets, clamps, replacement seals, and installation labor when estimating total system cost
