The EP 370 Series, manufactured by Protec Plastics, is a series of thermoplastic rubber plugs which features an easy-removal pull tab design. Whenever the tab is pulled, the base of the plug elevates upwards and inwards. After that, the plug releases in a rapid rolling motion that prevents any residue from being left on the threads or in the bore. The previously mentioned process characterizes the pull tab design.
This series is capable of tolerating a constant temperature of up to 120°C. In addition, it has a rolling release action that eliminates the debris upon removal. Also, the standard color of these rubber plugs is black.
