New Rifeng PAP clamping tool is redesigned to be easier and more accurate to use. The gripping handle is longer than before and provides larger lever force when pressing, this gives stronger compression on the sleeve and better seal after installation. The major improvement is two mechanical adjustors are installed on the tool so users can control the position of the jaw in order to manage appropriate pressing force during installation, therefore avoid the damage of jaw and fittings. The specifications of the jaws are 1014, 1216 and 1620, and others are coming up by the next improvement.
