Grease gun - air or battery powered has more force?

[RTcat]

Ignoring the convince of a battery powered grease gun (air compressor sits next to my bobcat in the shed), which will have better pressure/force for pushing grease into a zerk?

Getting tired of hand squeezing my the manual gun.

In looking at online reviews, air guns seem to have a better overall rating compared to the battery powered ones.

I have a 10 year old Lincoln battery and some generic like northern tool or something pneumatic, and I would say they battery powered one pushed more grease with one trigger pull. Add the convenience of the battery and it's a winner for me. Down side is that it is bigger and heavier with battery, but again my unit is older so I imagine the batteries are like every other cordless tool and better, stronger and lighter.

I have the Lincoln pneumatic grease gun....love it.I paid $65 for it on Amazon about 5 years ago..

It depends on the guns rating. If you want max power, look for one rated at 10,000 psi. A good manual lever one, a higher end air one and most good brand 18v cordless can reach this pressure.

If you have either M12 or M18 battery system, you can look for a bare tool.

I have the M12 (rated at 8000 psi & the M18 is rated are 10,000 psi) and love it. I use it mainly for my tractor. The manual one I had sucked and the pneumatic was OK but I had to bring my tractor to my garage/driveway and always risk grease blobs to clean up. With my M12, I go to my tractor or anywhere necessary and I also find it more powerful than the pneumatic I have.

The garbage Lincoln guns 20v at work are rated for up to 10000 psi. the even crappier 18v is rated for 7500 psi.

Battery has pretty good force, just don't buy the Lincoln they are very poor quality and do not last.

Air for durability sake. If you drop it which happens it is going to hold up better. Unless you plan on going out into a field some where and greasing a tractor pneumatic all the way. Lincoln Electric is what I used for our Air operated one but, it was brand new. Other then that we had 2 of the drum style ones.

Why do you need that much force cause 6000PSI will move a tractor trailer steer pin and raise the truck up some. If you are trying to break loose sticky zerks there are some other tools you might want to look at:

You fill it with grease and tap the end with a hammer. it forces the ball open hydraulically. I would also recommend something similar to these http://www.amazon.com/dp/B0040CWX7C/?tag=atomicindus08-20

I have the Snap-on 18V one and I've had no issues with it. Works great.

I have the better pneumatic gun from HF and it puts out so much pressure I blew the grease seals out in my trailer twice before I figured out to turn it down to 40psi... It almost works too good.

I did have to take the first one back but the second one is working great.

I agree. I use the electric when I am in the field doing repairs. I tend to use a hand pump in the shop, I honestly almost never use the pneumatic one. I feel that they puts out the least amount of grease per pump out of all of what I have.

My Lincoln air has only 6000 psi of force.

I had a Craftsman air model, worked ok, didnt last more then a couple months. Switched to the Lincoln (1162 IIRC) air grease gun and it has lasted under very heavy use. Never had a problem with lack of psi. IMO it would run circles around the Lincoln battery models, speed wise. Never compared it to the Milwaukees as they were not available at the time.

Me too--paid about that on Ebay around that time. I use it for greasing the dozen hubs on my old farm disk. It is a real chore to do it manually and the "machine gun" effect of the pneumatic makes it effortless. It takes three tubes of marine grease to get the job done, so doing it by hand was a horrible undertaking.

I can't comment on a battery one, though I'd imagine being cordless would have value.

I tried the pneumatic gun from HF. It didn't work well for me, wouldn't prime. I tried every trick, loosening the grease chamber from the pump head, removing the "bleed" screw, and I only got it to take a prime once. Don't know if it had a bad check valve or what, but it went back to the store. I have a lot of HF tools, so there's no bias here.

I replaced it with a Lincoln that is a pleasure to use. Install your new tube, screw the chamber on 3 or 4 turns and loosen the bleeder, release the spring rod, and then tighten everything up. Takes prime in two or three cycles. It has a much better hose and coupling as well. The air hose gets a little annoying when you're running around an implement, but it still beats a pistol grip gun by a long shot.

I am curious if the cordless guns can maintain their max pressure rating when the battery is only at 50 or 60%.

Yeah first one I had wouldn't prime but then I saw a video review where the guy showed how to manually prime it and mine has been fine ever since.
