Duff-Norton 8000 Series
Steam & Hot Oil Rotary Unions ®
Available in sizes ranging from 1/2˝ to 4˝, the
Series 8000 is designed for operation in a
variety of steam applications. The anti-torque
lug prevents rotation of the housing while in
operation. The special carbon graphite
bearing is lubricated by the process fluid and
requires no additional lubrication. Series

the standard 8000 Series with a special high
temperature seal ring for hot oil applications.
