ALUMINUM WASHERS

An aluminum ring can be used anywhere (except in the presence of certain aggressive acids) due to its resistance to corrosion.
Through special preheating, the structure of the metal ring softens further so that, when put under pressure, it can be incorporated into all uneven areas of the parts being screwed together.
Notice
When using sealing rings, you should take into account that the dimensions are specified as inner and outer diameters. If space is limited, the inner diameter is decisive, as a 10×12 washer can be replaced with a 10×14 washer or even a 10×16 washer.
