This Alemite 3053-B thread-forming fitting has an angle of 45 degrees and a 1/4"-28 special taper threaded end for applications where a grease fitting is needed for an untapped hole. The trivalent zinc plating gives it durability and makes it resistance to corrosion, exceeding a 72-hour salt spray test. It has a 3/8" hex size, and its 1/4"-28 special taper threading is for an untapped recommended hole size of .230" to .235" to create a leak-proof seal. This grease fitting holds in lubrication in the assembly being lubricated and is used for applications such as lubricating motor vehicles, construction and industrial equipment, and aeronautics.

Oil and grease guns are handheld tools that inject lubricant (dispensed from the barrel or cylinder cartridge) into metal mechanical assemblies. Electric and air-powered grease guns can dispense large volumes of lubricant in commercial applications, while battery-powered (cordless) grease guns are more suitable for mobile and remote applications. Manual grease guns (lever, pistol-grip, screw-type, push-type, and suction) vary in duty and have either a rigid or flexible hose extension for attaching nozzles or a nozzle with coupler for standard grease fittings. Oil and grease guns are used in a broad variety of applications including vehicles of all types, construction equipment, factory and agricultural machinery, and aeronautics, among others.

Alemite manufactures lubrication and fluid handling systems and components. The company, founded in 1918, is headquartered in Fort Mill, SC.
