MERCURY Resistant O-Rings and Seals
Mercury, also known as quicksilver, is a chemical element with the symbol Hg and atomic number 80. It is commonly used in thermometers, barometers, manometers, sphygmomanometers, float valves, and chemical and medical equipment. Mercury is also commonly used in fluorescent lighting, in batteries, and in some electrical switches and relays. Common industries that regularly use mercury include electronics, chemical processing, and pharmaceuticals.
When rubber is exposed to mercury, it can cause swelling of the rubber, which can then lead to cracking, tearing or loss of elasticity. Additionally, mercury can corrode metal parts, leading to further failure of the rubber seal. The rubber can also become brittle due to long-term exposure to mercury, leading to fatigue cracking.
