A grease gun (pneumatic) A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually from a grease cartridge to a grease fitting or 'nipple'. The channels behind the grease nipple lead to where the lubrication is needed.
Silicone grease is widely used as a temporary sealant and a lubricant for interconnecting ground glass joints, as is typically used in laboratory glassware.Although silicones are normally assumed to be chemically inert, several historically significant compounds have resulted from unintended reactions with silicones.
[4] [5] Powdered solids may also be used as thickeners, especially as absorbent clays like bentonite. Fatty oil-based greases have also been prepared with other thickeners, such as tar, graphite, or mica, which also increase the durability of the grease. Silicone greases are generally thickened with silica.
Grease fitting on a bearing A grease nipple on the driver's door of a 1956 VW Beetle. A grease fitting, grease nipple, Zerk fitting, grease zerk, Alemite fitting, or divit is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.
Silicone caulks and rubber components are often used in automotive applications. In the automotive field, silicone grease is typically used as a lubricant for brake components since it is stable at high temperatures, is not water-soluble, and is far less likely than other lubricants to foul. DOT 5 brake fluids are based on liquid silicones.
The M3 is an American .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. [12] The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun , but was cheaper to mass produce and lighter, at the expense of accuracy. [ 12 ]
The rubbery, vinegary-smelling silicone caulks, adhesives, and aquarium sealants are also well-known. PDMS is also used as a component in silicone grease and other silicone based lubricants, as well as in defoaming agents, mold release agents, damping fluids, heat transfer fluids, polishes, cosmetics, hair conditioners and other applications.
In 1999, an estimated 37,300,000 tons of lubricants were consumed worldwide. [4] Automotive applications dominate, including electric vehicles [5] but other industrial, marine, and metal working applications are also big consumers of lubricants.
