When installing the perfluorinated
0-ring, in order to reduce the wear and tear of the perfluorinated 0-ring, we can use grease and other methods to reduce wear, and pay attention to the tensile strength during installation to prevent Deformation, etc. So, what should we pay attention to when installing perfluorinated 0-rings? (1) Lubrication During the installation of elastomer seals, the use of grease can reduce wear and seizure. In general, a thin lubricating film is necessary for installing O-rings, because perfluorinated seals are used in harsh working conditions, and lubricating oil can improve the high temperature carbonization cracking resistance of the seals. In most cases, the sealed medium is used as lubricating oil, fluorinated oil, such as Krytox or powdered graphite can also be used as lubricating oil. Even if lubricating oil is used, care should be taken to reduce the damage to the O-ring during the seal installation process. (2) Stretching The elongation at break of most perfluoroelastomers is between 120% and 170%. When installing the 0-ring, you must pay attention to the elongation data to prevent the 0-ring from breaking beyond the elongation at break. Generally speaking, the stretching degree of the installation of 0-ring should be controlled within 50% of the elongation at break. If it is difficult to install, the 0-ring should be softened in hot water and installed correctly. The method can avoid the damage of the seal. Through the correct installation method, we understand the matters to be noted. We know when installing the perfluorinated 0-ring, what to do to reduce wear, etc., so that the number of scrapped 0-rings will be reduced. So, do you know what to pay attention to when installing?
