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.
This helps ensure that the gun does not discharge in an unsafe manner, causing the nail to become an unrestrained projectile. Due to their potential for causing personal injury, OSHA regulations in the US require certification specific to the tool being used before any person is permitted to rent or use powder-actuated equipment.

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.
The most common causes are accidents with grease guns, paint sprayers, and pressure washers, but working on diesel and gasoline engine fuel injection systems as well as pinhole leaks in pressurized hydraulic lines can also cause this injury. Additionally, there is at least one known case of deliberate self-injection with a grease gun. [2]
The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser", owing to its visual similarity to the mechanic's tool. [14] The M3 was intended as a replacement for the Thompson, and began to enter frontline service in mid-1944. By late 1944, the M3A1 variant was introduced, which also saw use in the Korean War and later conflicts.
Most current gas systems employ some type of piston. The face of the piston is acted upon by combustion gas from a port in the barrel or a trap at the muzzle. Early guns, such as Browning's "flapper" prototype, the Bang rifle, and the Garand rifle, used relatively low-pressure gas from at or near the muzzle. This, combined with larger operating ...
Autofrettage is a work-hardening process in which a pressure vessel (thick walled) is subjected to enormous pressure, causing internal portions of the part to yield plastically, resulting in internal compressive residual stresses once the pressure is released. The goal of autofrettage is to increase the pressure-carrying capacity of the final ...
On March 22, 2020, Eric Smidt directed Harbor Freight to donate its entire supply of N95 masks, Face shields, and 5/7 mil Nitrile gloves to hospitals with a 24-hour emergency room. In June 2022, Eric & Susan Smidt donated $5 million to the Holocaust Museum LA , which will allow the museum to double its campus in Pan Pacific Park .
