These KF-40 Weld Socket Flange fittings follow ISO-KF standards and have a flange size of NW-40. 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.

The flange is sized by the largest nominal I.D. (in, mm) tube that can be welded to it. Standards sizes are: KF10, KF16, KF25, KF40, and KF50. Although these sizes are used in North America, the true nominal bore is often that of standard inch dimensioned tubes.
