SE Series Rotary Unions
The SE Series rotary unions / rotating joints are designed for applications with high pressure requirements and limited space. All SE series unions offer SAE-4 and o-ring flange connections. Originally designed for machine tool work holding applications, these versatile unions are currently used in a number of industries. The SE Series rotary unions / rotating joints are available in 2, 4, 6, 8, 12, 16 & 24 passage versions and incorporate DSTI’s exclusive DynaSeal™ seals, which are suitable for vacuum & bidirectional pressures up to 7500 psi.
