DSTI - Model SPS Series - 1-Passage Rotary Unions & Joints

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 NPT threaded shaft connection, a female NPT threaded housing connection and two tapped holes on the end of housing for easy equipment integration. The shaft, housing, seal material, and design makes this an excellent solution when transferring air/gas (under pressure or vacuum) from a stationary source to a rotating component. Need to combine air/gas 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.
