Made to tighter tolerances than other compression fittings, these are designed for high-precision applications. Also known as instrumentation fittings and flareless fittings. They come with a nut and a single sleeve (ferrule). The sleeve bites into tubing as you tighten the nut to create a strong seal. Fittings are 316 stainless steel for excellent corrosion resistance. A molybdenum disulfide coating on the nut acts as a lubricant for easy installation.
