 Our new 6900 series has improved upon and replaced our 6800 series Multi-Passage Flange Mounted Unions, also known as Multi-Passage Flange Mounted Rotary Joints.
These multi-passage flange mounted unions are designed
for extremely high hydraulic pressures while running
at moderate RPM’s. We offer you a design that
incorporates 2 ball bearings and our unique “O”
ring slipper seal design that provides you with a
product that has a longer life, lower torque and better
performance that standard O-ring loaded slipper seals.
All of the multi-passage flange mounted
unions within the 6900 series will provide an even
loading of the entire seal interface area, tremendously
high extrusion resistance, hardened and ground shaft
and an ultra hard low friction surface. All multi-passage
flange mounted union models are available with NPT,
BSP, SAE or Metric Threads and Aluminum or Steel Housings.
If you prefer, all stainless steel construction is
available upon your request for superior corrosion
resistance.
All units are CAD and RFQ Interfaced enabled. If the models listed do not meet your needs, please contact our experienced knowledgeable sales staff and they will be happy to meet your requirements.
