Alemite 6638-B Grease Gun Rigid Extension, 12 1/8" OAL, Coupler #308730, 1/8" Male NPTF

This Alemite 6638-B grease gun rigid extension has an overall length of 12-1/8", an Alemite 308730 hydraulic coupler, a 1/8" NPTF (National Pipe Thread Fuel) male end, and is used to extend a grease gun to reach grease fittings that are otherwise difficult to get to. This rigid extension has a triple jaw assembly that with a slight pushing action secures it onto fittings for a tight seal while the lubricant is pumped into the fitting. It has a 25-degree sealing angle for leak-proof transfer of lubricant. This extension can be used with all Alemite grease gun models and uses Alemite coupler 308730. This rigid extension fits onto the outlets of grease guns that inject grease into standard grease fittings and are 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.
