Confirm your equipment's mating thread matches the rotary joint thread specification. Download the 2D drawing for exact dimensions.
Use PTFE tape or liquid thread sealant on the male threads. Do not overtighten — hand-tighten plus 1/4 turn maximum.
If your model includes an anti-rotation tab, secure it to a fixed point. Never let the body rotate freely with the shaft.
Use flexible hoses to avoid side-loading the rotary joint. Install a filter (40 micron or finer) upstream to protect the seal.
Run at low pressure (0.2 MPa) and low speed for 5 minutes without load. Check for leaks, then gradually increase to operating conditions.
