Product Description These KF-16 4-way cross vacuum fittings follow ISO-KF standards and have a flange size of NW-16. They are commonly used to build foreline vacuum plumbing and process systems. They are often called quick flange fittings because they are quick to assemble. A circumferential clamp and centering ring form the vacuum seal between the connecting flanges. The centering ring contains a rubber elastomer o-ring. The standard sizes for quick flange fittings are KF-10, KF-16, KF-25, KF-40, and KF-50 with flange sizes NW-10, NW-16, NW-25, NW-40, and NW-50, respectively. They are made of corrosive resistant stainless steel. Very strong and clean machining work. Low price with high quality! With our competitive pricing and finishing time, we are confident that we can underbid other online/offline scientific vacuum instruments vendors.
