Confirm your equipment has G1/8 (BSPP) female threads or appropriate adapters. The BP-3P-0007 uses G1/8 male threads with 3× M5 mounting holes on the rotor side and 3× ?6 mm through-holes on the stator side. Download the 2D drawing for exact dimensions.
Apply PTFE tape or liquid thread sealant to the G1/8 male threads. Hand-tighten first, then tighten to 8–12 N·m with a wrench. Do not overtighten to avoid thread damage.
Use the 3× M5 mounting holes to secure the rotary joint body to a fixed bracket. Never let the body rotate freely with the shaft. Torque M5 bolts to 3–5 N·m.
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.
