Alemite 500-E Grease Gun, LockNLube® Grease Coupler, and swivel


The right grease gun and the right grease coupler for the job.  With the LockNLube® Grease Coupler, you have both hands free to operate your grease gun. This Alemite 500E Grease Gun comes with an 18″ hose, swivel, and LockNLube® Grease Coupler, and a spare seal kit. 

  • Develops up to 10,000 psi pressure
  • Rugged and light weight die cast aluminum head
  • Vinyl cover for a comfortable and sure grip
  • 3 way loading (14 ounce grease cartridge, suction, or fast refill from Alemite Loader Pump)
  • Bleeder valve


This Alemite 500-E grease gun comes with an 18″ hose, LockNLube® Grease Coupler, in-line hose swivel, a spare seal kit for the coupler, and the patent-pending Loop & Lock. It has a cylinder capacity of 16 oz., delivers grease at pressures up to 10,000 pounds per square inch (psi) at a rate of 1 oz. per 20 strokes, and can load grease three ways: 14 oz. cartridge, suction, or fast refill from an Alemite loader pump. A lever mechanism provides standard volume output. This grease gun has a die cast aluminum head for lightweight durability, and the lower portion of its lever has a vinyl cover to make it easier to grip. We also include a swivel so that the grease hose can rotate freely. This allows you to position the trigger on the LockNLube® Grease Coupler however you like without spinning the grease gun.

We unbox the Alemite 500-E bundle to show you what’s included to make this the “best lever grease gun on the market”.


We love the way that the Alemite 500 works, but when we were done using it, there was no good way to tame the grease hose and prevent it from getting grease on whatever it touched. We created the patent pending “Loop & Lock” system to tame the grease hose, prevent accidental spillage, and help keep your equipment, and your clothes, clean. The LockNLube® Grease Coupler locks on to the inert grease fitting to hold it in place until you are ready to use the grease gun again. It also serves as a handy way to carry or store the grease gun. This feature comes standard on all of the Alemite 500 grease guns that we sell.



Loop & Lock makes carrying grease guns easy and mess-free.
