GENERAL / Tightening Torque Screw-In Connection Depending on types of screw and sealing, different types of screw fittings are used. IMPORTANT: Be sure to confirm that the thread pitch and thread type (tapered or straight) are the correct type before using any screw-in connection. Seal Tape Application Seal tape is used to seal clearances between male and female threads, so as to prevent any leaks between threads. Be sure to apply just enough seal tape to fill up thread clearances. Do not overwrap. Application Procedure Confirm that the thread surface is clean and, free of dirt or damage. Apply seal tape around threads as shown. Wrap seal tape in the same direction as the threads.
