I find it beyond stupid for this manufacture to sell a vacuum pump while providing the directions manual (which is nice) but within directions it says to fill the oil tank with the oil provided & run it for a set period of time, dispose of that oil and refill the vacuum pump. The problem is they provide you with only enough oil to fill

I bought this adapter to adapt my Mastercool 84772 manifold set which uses the female ACME thread on the yellow hose to my vacuum pump which has a male 1/4" flare fitting. One thing that nobody has mentioned is that this FJC adapter does not have an insert in it; it is just a hollow straight through fitting. Most new R134a manifold

Buy this updated part from Yellow jacket. The original part (same part number) is a plastic/rubber sleeve that goes around the two shafts. Really poor design but nice to see Yellow Jacket step up and update the design and at a very reasonable price. If you have the sleeve type, replace it sooner rather than later. How do you know the

I just installed this 93047 coupling on my older YJ 6-CFM pump and it is now up and running again. The old coupling was original to the pump and had a splined plastic tube setup, similar to what JB uses on their pumps, but a little longer. This new YJ coupling design uses a rubber spider in between the metal halves instead of the plastic

This unit fixed my Yellow Jacket Vacuum Pump and it is a real Love Joy coupler! Only thing I gave up was the sheer of the coupler is the pump froze up however the motor thermal overload will keep it safe. This is a far superior coupler than the Lexan Unit that came with the

This pump worked great. On calibrated manifold gauges it pulled 29.8 psi. You can't here it run from three feet away.. I have done 3 cars with it so far and have run it over 5 hours between the 3 cars without it shutting off or overheating. Maybe the difference between how i use it and some other people use it is i don't use the vacuum

Ok so for the price, its a really good pump for small jobs. This pump has not leaked any oil and its surprisingly quiet. You would expect it to sound like an air compressor of comperable size, not so. It sounds more like a pump for a large fish tank. The brass fitting is a quick connect I added. The red cap is where you add the oil. The

Got the pump in order to pull a vacuum on my car's A/C system as part of a r22 to r134a retrofit. Once all of the o-rings were replaced I connected the pump to the gauge set and started the pump up. It managed to pull very close to 30 Hg so it is a very capable pump for the price.
The pump does not run hot nor does it make a lot of

I am an unbiased, verified purchaser of this pump. I am also a weekend mechanic, working on my car, as well as family and friends. I bought this pump on October 12, 2011 (per amazon order history), and have easily done 10+ cars A/C work. It still runs strong as it did when I bought it 6 years ago. It only has to do one job and it does it

I used this to evacuate an AC system i installed in my car that didn't come with factory air. i ran the pump for about 45 minutes and my manifold gage indicated a vacuum of 21" Hg which was not as low as i was hoping for. i did some research online and found a chart which indicated that at my elevation (5,000') the best vacuum i could

Surprisingly, this pump performs above my expectations for its specs and price tag. The unit comes with a 1/4" fitting already installed for the older R12 1/4" gauges instead of a dual port fitting (both 1/4 & 1/2) as shown in image. I have a set of CPS MA1234 guages that has a 1/4 " female fitting on the yellow hose and they

I purchased this to use for resin impregnating my wood turning blanks. It pulls a much higher vacuume than the venturi products that are available. It's not too noisy which is nice if you happen to be resin impregnating on your kitchen table. (I have a WONDERFUL, wife, generous of spirit and MOST forgiving of her husband's faults.)

I bought this unit in December and finally had time to set up some stabilizing on March 8th. This unit does not draw the vacuum as it advertises. I tried two different pots and it will not draw down enough to seal the lids after 20 minutes of running with weight on the lids. Total waste of my cash. Don't even consider this for wood

Used it to install/vacuum a couple of dual-circuit Pioneer mini-splits. I ran it continuously for 6 hours on each circuit and not a single problem. 5-CFM is more than i really needed but this was the best (in my opinion) 2-stage pump (for deep vacuuming) i could get for the money so no complaints. Cant go 5-stars because it has been run

Was able to pull a vacuum down to 37microns (on a short hose and CPS VG200 gauge as a test) which should be plenty good for my purposes. Overall seems sturdy. I worry a little about the choice to use plastic for the base and whether that may crack over time but it will probably be OK as long as the pump is not handled too roughly, time

I am using this to pull vacuum on vacuum bags for carbon fiber resin infusion. The manual notes that you're suppose to let the pump run through a break in period.

Build quality appears to be quite nice for the price, for occasional use it's a good value.
1) Must unscrew the exhaust fitting to fill oil, as other reviews have stated if you pour the oil into the exhaust fitting it has to filter down through the exhaust.

Much quieter than I expected. It pulled down to -30 in-Hg very quickly and held it there.

Compact, portable, easy to use. The handle doesn’t get in the way of the valves so that I can easily add hoses or whatever I need. Powerful enough to handle multiple tasks at once.

I received the pump just in time to complete an urgent project. The directions include an "oil flush" procedure, so I filled the pump with oil, ran the pump for 1 minute, then drained the oil .

It is a toy single stage pump, but for the price it actually seems to work reasonably well. It is rated on the compliance plate at 5 Pa ultimate vacuum (or about 37.5 micron). I get about 120 micron out of it with nothing but the thermocouple gauge. Like most pumps it will bubble and spit some oil out when pumping a gassy load, a small

Worked well and used it right out of the box. Set it aside for three weeks and came back to find a good sized puddle under the oil housing on top of the base. It had dripped down onto the bench.

The pump ran just fine the first couple times I used it. It did the job I bought it to do. It didn't come with the proper attachment for what I wanted to do with it which is put a vacuum on an automotive air conditioning system but I knew that up front.

This thing is awesome. In my line of work we need to vacuum down the systems to a consistent below 500 microns. Meaning, you pull down to below 500 and wait. Because the micron number will rise, possibly past 500 again. This vacuum pump pulls down to 136 microns on average. And then depending on the system I may or may not have to do a

The pump works, no question about that.

Nice pump for the money. Pump ran smooth, quiet and did it's job. You will see some complaints about oil residue on the pump, they are tested at the factory and drained but some remains in the pump.

Have been using it as an affordable option in a lab environment as a scrubbing pump in series with a 90k rpm turbo vacuum pump that, when combined pulls 9 microns.

It is VERY quiet, down around the 15-20 decibel range even under vacuum (around 65db is human voice rating). It sits still on my workbench and doesn't wander around even though it is very light.

The suction is good on this little pump and it's very quiet once it's not pulling a large volume of air. Only complaint is if it's running and holding a vacuum, the motor housing gets too hot to touch within 5 minutes or so. I also notice a definite oil smell once it gets hot, not exactly like burning oil but it's there.
