Series CPT Plugs have the same configuration and dimensions of standard Tapered Plugs but with an integral center pull-tab which facilitates insertion and removal of the plug. The tab extends well above the plug body, making it easy to grasp. Since the tab is molded fully into the end and side walls of the plug, it will not break off during plug removal. The concentric design of the CPT allows a straight-pull removal without disturbing O-ring fittings.
