Asbestos-free, shape C
An asbestos-free copper ring can be used anywhere (except in the presence of some strong acids) due to its corrosion resistance. Via special preheating, the metal ring's structure softens further so that, when under pressure, it can embed itself into all the uneven areas of the parts to be screwed together.
NoticeWhen using sealing washers, it should be noted that the dimensions are specified as internal and external diameters. If the correctly sized washer is not available, select the washer based on the internal diameter; for example a 10x12 washer can be replaced with a 10x14 or even a 10x16 washer.
