ISO-F Bored & Blank Flanges

Pfeiffer'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 and are also available in 316L stainless steel; some additional sizes are available for increased corrosion resistance.

Bolt and retainer ring sets effectively help convert an ISO-K flange to a rotatable ISO-F flange.
