ISO,LF Flanges and Fittings

Dimensions LF, ISO Flanges, Fittings and Definition

The ISO large flange standard is known as LF, LFB, MF or sometimes just ISO flange. A larger version of the KF (QF) flanges, the flanges are joined by a centering ring with an elastomeric o-ring seal. ISO stainless steel vacuum fittings are for tube sizes ranging from 2-1/2″ through 24″ diameters. ISO design is ideally suited for applications requiring rapid and frequent assembly and disassembly.
