ISO-F Bored & Blank Flanges

Nor-Cal Products ISO flanges and hardware are manufactured to the International Standards Organization specification so they can be mated to other manufacturers'™ ISO flanges. Normally our standard material is in the low carbon range for 304 stainless steel. For increased corrosion resistance, some sizes are available from stock in 316L stainless steel. 

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