This Alemite 500-E grease gun comes with an 18″ hose, LockNLube® Grease Coupler, in-line hose swivel, and a spare seal kit for the coupler. 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 our favorite lever-action grease gun on the market (other than the LockNLube Lever Gun, of course).

The Best

I purchased the Lock N Lube couplers over time, then finally bought a 500 Grease Gun. Absolutely the best grease gun I have ever had in my 50 years plus greasing farm and ranch equipment!

Good quality product

Great grease gun for the price and well made. The Lock N Lube device works well for grease fittings that are not too short or recessed in a small diameter hole. I love the swivel on the hose. Good product overall.

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

I had 4 grease fittings on my Yamaha X2 that could not get to receive grease. Thus started my investigation. I went to my dealer and search the the internet. That is how I came across the LOCKNLUBE COMPANY, The LockNLube Grease Coupler is worth its weight in gold period. No problems now with the above stated fittings. Their grease gun also comes also with a swivel on the hose. What a perfect solution to stop fighting the pressure and position of your gun. I wish I would have found this company years ago.
