Large-Flange® ISO vacuum flanges are an economical
system of reusable interfacing stainless steel vacuum
fittings for larger sizes of tubing from 2-1/2 thru 20
inch. Vacuum seal is by compression of an o-ring between
two like flanges which can be either Claw-Clamp or Bolt
type. Standard components in this catalog are supplied
mounted on Claw-Clamp flanges. These can be mated to
bolt flanges with a Rotatable Bolt Ring assembly.
Assemblies are bakeable to 200°C intermittent and 150°C
sustained. Operating pressure is 30psig positive. Viton®
o-rings may require periodic replacement.
