They are unsheathed and butt welded. Commonly used to build foreline vacuum plumbing and process systems. They are often called quick flange fittings because they are quick to assemble.

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.
