The 15 Ra finish on the interior of these fittings creates an ultra-smooth surface. Also known as ultra-high-purity fittings, they are packed in a Class 100 clean room to prevent contamination. They are commonly used in semiconductor applications. Fittings use a metal gasket (sold separately), which generates fewer particles than a rubber gasket and creates a strong seal in high-pressure and high-vacuum applications. Fittings are 316 stainless steel for excellent corrosion resistance.
