ISO-K Bored & Blank Flanges

Pfeiffer Vacuum Valves & Engineering's ISO flanges and hardware are manufactured to the International Standards Organization specification so they can be mated to other manufacturers'™ ISO flanges.

Typically our standard material is in the low carbon range for 304 stainless steel. Available in 316L stainless steel, some sizes are available for increased corrosion resistance.
