i am looking for a low profile professional service jack ,does HFT has any discount at this moment
Thanks
Depends on your needs.
I have the 2 ton low pro jack from HF and its been great. It lifts really high (23+ inches) is rated just enough for most of my vehicles and has given good service for the last year or so that Ive had it.
The aluminum one at HF ***** - my broke after a couple uses - literally the metal broke.
You can get the 2 ton one for about $120. Just google 'HF 2 ton low profile jack coupon.'
"The Best", "Professional" and then asking about Harbor Freight discounts...
You my friend, are seriously confused.
Do you want the best or do you want cheap? You cannot have both.

+1 for the 2 ton high lift. i bought it to use on my 95 f350 diesel dually.. its asking a bit much from it, but it works fine.. great jack for the money, and the highest lifting one they have... t - handle is really nice, and the top mounted release valve it nice too..

And for SNAP-ON lovers, the new FJ200, 2 ton model. Apparently, made in USA. $$$
Video below.
I have a low profile jack on my want list...this looks to be what I need. I wonder if my industrial rep can get me one.
I did some quick research after reading about the USA claim, unaware of any domestic company producing low profile jacks similar to the FJ200. I simply went to SO's website where it claims they are made in "CHN", which Is the country code for China. Tricky... I did see where a snap on dealer was praising them as U.S. Made, Snap On's website has been wrong before, but I'm leaning towards towards it being correct in this case.
Thanks I will look in to it some more. That's a lot of money even with a discount for a China made jack.
The snap on jack is assembled in the USA in greenville south carolina its their design they own the company that assembles it.
Using u-cups for the pump piston is silly since the u-cup should be on the main ram and O-rings should be on the pump pistons. O-rings are two way seals whilst u-cups are one direction seals. The pump piston requires a two way seal to draw oil efficiently from the oil tank and then to push it into the cylinder. A new u-cup might work well when new but its efficiency will drop faster over time than an o-ring. Plus, ucups are more expensive to replace and subject to availability if a reapir kit is not found. As a matter of fact, many early imported bottle jacks and mini jacks used u-cups as the seal for pump pistons. At some point, the manufacturers started using both an u-cup and an o-ring for the pump piston, most likely because the u-cup would be less efficient drawing oil and the oring would then do that job. After that set was used for some time, the u-cup was removed and only the o-ring was used and that is what we still have today, at least in the imported jacks. So advertising that a new jack has u-cups in the pump pistons is not such a great thing, more than an advance, it is going backwards to things that were tested and discarded long ago.
I only saw the video for the Snap On, I did not go to their web site to check the specs as I was just presenting a low rise model for the OP, so the information about the use of an u-cup in the ram was unknown to me at the time of my posting. It is a good thing that Snap On took the care to include the use of an u-cup in its jack. Others don't care to do it. I don't care much about Snap On so I visit their web site between never and seldom.
The mention of premium u-cups used in the Snap On jack does not necessarily means they are using loaded u-cups in the pump pistons, unless the web site specifies so (have not been there yet). If they use loaded u-cups, then it is ok, if not, time will tell.
As for the use of only O-rings (and retainers) in imported jacks as a main seal, well, these should be way cheaper in volume than u-cups, so it is understandable that companies may want to use only o-rings instead of u-cups to save some pennies. Anyway, most customers don't care or don't know about the seals in the jacks so they will buy whatever is for sale. As for longevity, maybe the quality of the materials used today may not be as not as good as earlier materials, but anyway, seals are supposed to be changed at some point in time and the companies selling seals count on that. Seals, of any material, will not last forever. Other types of hydraulic equipment gets the seals serviced regularly, after a set number of hours, or if these fail before that set numbers of hours, but floor jacks seals are expected to last 20-30 years, something which is very optimistic and unlikely. There have been some cases were seals supposedly lasted many years (25+)but that would be an exception, not the norm.
Poly u-cups should work well as piston seals as one of the "qualities" of the poly u-cup is that it seals better at lower pressures than regular u-cups. The o-ring turns the loaded u-cup into a squeeze seal at low pressures whilst the unloaded u-cup is just a compression seal with less capabilities at low pressures. This does not means that the regular u-cup will not seal at low pressures, just that is not as good as a squeeze seal, like an o-ring or a loaded u-cup. On the long run, a regular u-cup may lose efficiency ( may depend on the tolerances maintained and quality of materials) before an o-ring or a loaded u-cup will.
As stated in the HITECHSEALS.COM web site:
The O-Ring Loaded U-Cup is a unique design that combines a precision molded "U" configuration packing with an elastomer loader. This seal was originally designed to improve the low pressure sealing capabilities of a
standard lip type packing but the design principle has been effective in dealing with high and low temperature and pressure extremes, including vacuum. While originally designed as a unidirectional sealing device, with the proper design and accessories, the O-Ring Loaded U-Cup can also be used as a bi-directional seal.
The basic theory behind the O-Ring Loaded U-Cup is that when you add a "loader or energizer" to a lip seal, you turn it into a squeeze seal that provides high sealing force at low pressure. As the system pressure
increases, the lip loading also increases, automatically compensating for the higher pressure while maintaining a positive seal. A rubber energizer typically has a better compression set, or memory than urethane and will
enable the U-Cup to have a longer life expectancy.
Anyway, if a manufacturer decides to use unidirectional (unloaded) u-cups in the pump pistons, (instead of bi-directional seals), and these fail before expected, what do they care, better for them if they sell a repair kit. They just want to sell jacks, after that (when the warranty ends), it is the buyer's problem.
Just remember, regular u-cups were designed as unidirectional seals, so buyer beware. If anyone wants bi-directional use, get loaded u-cups or get o-rings.
I really want to buy a quality low profile jack this years that will last. Seems like we have the best jack guys on the case, thanks..![]()

It's both the best, and as low profile as they get. It's over three feet long and weighs 120 lbs:
