RPV O-Ring Clips and Installation Tools 


The Preferred Engineering O-Ring clips speed the installation of the RPV O-rings into the RPV head. The clips are easily and reliably installed with a simple push over the installed clip post. The tool secures the clip while the installer positions the clip and simply pushes the clip over the post to secure the O-ring. Removal is made simple and easy with the use of the hooked removal tool.
