The 2-passage, GPS Series rotary unions feature specialized sealing technology suitable for vacuum and bidirectional pressures and two independent flow passages capable of transferring different media types simultaneously.
The stainless steel construction is suitable for hydraulic, pneumatic, coolant, water, and other corrosive media types. Carbon steel models are available for applications that do not require water or corrosive media transfer (see GP Series).
GPS 2-passage models with NPT thread connections consist of a unique shaft configuration for easier installation, allowing the choice of mounting the shaft connections using the threaded passages or O-ring face seal glands for flush mounting the union to an interface. GPS 2-passage models with BSPP thread connections are not available with O-ring face seal glands.
Need to combine fluid with electrical power, signal and/or data transfer? No problem. The GPS Series rotary unions are designed to integrate directly with our standard electrical slip rings.
