Features and Benefits

FEATURES & BENEFITS
9000G Series Water, Steam & Hot Oil High Temperature Rotary Union

Superior Sealing Performance

Bellows Sealing System provides superior sealing performance throughout the wear life of the Rotary Union.

Designed For Dirty Media Applications

Debris in contaminated media will not be captured in the Bellows Sealing System, which reduces clogging.

Maintenance Free

The 9000G is maintenance free because there is no rolling element bearing, therefore no lubrication is required.

High Temperature Applications

Offers the same design as the standard 9000 Series, but utilizes carbon graphite bearings for high temperature applications.

Ideal For High Temperatures

The thrust collar allows for thermal expansion, making this an ideal union for high temperature, general purpose applications.

Flanged Mounted Units Available
