Product Description
The Lesker QF items are Quick Flange components and are also known as KF Klein Flanges. QF is a simple, flexible O-ring vacuum flange system. It is so simple, and flanged components so inexpensive, that QF components are often bought in preference to weldable QF flanges. They are also compatible for vacuum sealing with KF flanges of the same size.
