Installation and Fitting Points: Clean the port threads and sealing surfaces before installation, ensuring no burrs or oil contamination. Apply a thin film of oil to the O-ring, pre-tighten manually, and then tighten with a torque wrench to 25-30 N·m.

The thread engagement length should be ≥10 mm, and the O-ring compression should be 0.3-0.5 mm. After installation, check for leaks and looseness, and ensure the port protection is in place.

Use a special wrench for disassembly to avoid slipping the hexagonal head. When replacing, it is recommended to replace the O-ring with a CAT 12×2.65mm one.

For long-term storage of equipment, install this protective cap to prevent port corrosion and the entry of impurities.
