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.
