Center Ring

Center Ring Center ring belongs to a connecting part for a vacuum pipe fittings such as a pipe, a pump and a valve. When vacuum system applied, due to the difference of conditions, there is no uniform standard, so we must regulate what is the standard. The combination of the center ring can be used for the sealing connection…
