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.
