Installation Procedure

1. Thoroughly clean both the pipe ends and the fitting interior using an appropriate solvent and lint-free cloth. 2. Apply a suitable lubricant to the pipe threads or the internal surface of the fitting, depending on the connection type. 3. Carefully screw the pipe into the fitting, ensuring straight alignment to avoid cross-threading, and tighten to the manufacturer's specified torque.
