- An aluminium 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.
When using the sealing rings, you should be aware that the dimensions are specified in the inner and outer diameter – if the space is tight, the inner diameter is decisive, as a 10x12 washer can be replaced with a 10x14 or even a 10x16 washer, for example.
