SPS Single Passage Rotary Union
The single passage SPS Series rotary unions are small, lightweight and corrosion-resistant featuring aluminum construction with a stainless steel shaft.
The SPS Series rotary unions integrate directly with our EST electrical slip rings
to combine a single fluid passage with power, signal and/or data transfer See example.
