The SPS Series single passage rotary unions are compact, lightweight and corrosion-resistant featuring a stainless steel shaft and hardcoat anodized aluminum housing. All models come standard with a male 1/4"-18 NPT threaded shaft connection, a female 1/4"-18 NPT threaded housing connection and two tapped holes on the end of housing for easy equipment integration.
The shaft, housing and seal materials and design makes this an excellent solution when transferring coolant, hydraulic oil or air/gas (under pressure or vacuum) from a stationary source to a rotating component.
Need to combine fluid with electrical power, signal and/or data transfer? No problem. The SPS Series rotary unions are designed to integrate directly with our standard thru-bore electrical slip rings.
