Dual Passage Rotorseal

Dual passage rotorseals allow the transfer of media thru two separate shaft passages located on the same shaft end. Each passage can be used for a different medium; for instance, air for clutch actuation and oil for bearing lubrication. Inlet and outlet ports have American National Pipe Threads. Airflex has five (5) dual passage rotorseal product lines.
