Description
Compression reducing unions bridge two different tube outside diameters on one straight axis with double ferrules both sides. FerruleX covers reducing pairs inside the 3–25 mm / 1/8"–1" envelope in SS316, SS316L or SS304. Panel redesigns and OEM machines that mix metric and fractional tubing need this fitting instead of two adapters. Pressure follows the smaller tube’s wall rating; plan near 1000 PSI unless you order the HP series. Put both tube OD values on the FerruleX RFQ so the factory pulls the correct reducing blank from stock. List the larger OD first in notes so purchasing and the factory read the same reducing direction.
Always list the larger OD first in your notes so purchasing and the factory read the same reducing direction. If one side is fractional and the other metric, say so explicitly to avoid near-size mix-ups. FerruleX holds common reducing pairs for fast shipment and machines odd pairs after drawing approval.
