Air Grease Gun

djg · Jun 10, 2005

Anyone looking at this old thread might be interested in a really good grease gun, it is made in Australia and is MacNaught brand. I have seen it at Grainger and in some professional tool catalogs. Basically, it goes on top of a five pound can of grease. It has a foot operated spring loaded plunger that pumps the grease into a six foot hose to a pistol grip gun. The gun has a high flow or high pressure selector. It always works. The only problem is you can crush the grease can with foot pressure. We made a heavy steel can that solved that. Gave up on air guns, too much trouble.

I just bought the professional one at the local sear hardware too. It has a air purge at the top to let the air seep out so you can tighten the tube and then use the air release at the top. $50 onsale for $29 and then $15 off for opening a Sear card which will be cancelled immediately.

I'm just wondering if all grease is the same or if theirs an advantage to one type over another.

That Macnaught is a $230 grease gun. It better be perfect. Here's the link to the site. http://tinyurl.com/9eops

Thanks for the link. We use the K6 minilube gun. It is 168.00, not 230.00, but pricey. It does work. Sometimes I don't realize the price of things the company buys for us at work.

I've been wondering about that also. Not the quality of the grease, cause I know there's better grease, but what I've been curious about is the packing of it. Do some companies do a better job of eliminating air pockets in the middle of the tube?

As for the air bleed button. I've tried and tried to get some sort of results from that without any luck. Either it's too complicated for me, or it doesn't do anything. I figure that since it's there, it must do something, but what and how has me baffled.

I believe that the tubes are filled by machine and the air pockets cannot be avoided unless the grease were heated to the point where it would flow like water. Since this isn't possible, I believe that all grease tubes are created equal. You might try keeping them standing on end, rather than on there side so the grease will settle to the low end. Remember the old days when you would tap the top of the cigarette pack on the table to compact the tobacco? Give that a try first with the grease tubes before installing them. Might just work... /forums/images/graemlins/grin.gif
