Deublin | 1379-160C | Service Kit

Oil rotary union with four independent passages for applications such as clamping and unclamping, work piece or tool sensing, and spindle cooling. The vent between passages 2 and 3 allows using two different media without cross-contamination. For example, water in passages 1 and 2 and hydraulic oil in passages 3 and 4 is possible. Made of stainless steel and brass components that resist corrosion, a hardened chrome sealing surface, elastomer-energized seals, and dual, widely-spaced ball bearings that absorb large side loads.
