How to install a MOSMATIC rotary union?

Ensure the rotating shaft is clean and properly aligned with the machine's rotating component. Tighten the 3/8 in threaded connection to the manufacturer's torque specification. Verify that the union is not subjected to side loads or misalignment, which can reduce seal life at 30 RPM.
