Company Features
1. Dms Seals Technology Co.,limited has strong economic strength and technical strength.
2. We emphasize customer focus. We ensure that all aspects of the company put customer satisfaction first. Welcome to visit our factory!
We used this jack to lift 4 pieces of machinery (two of which were CNC machines) in order to position skates under them for moving. Worked as expected. Good value. Quick shipping.
Paid for itself the first day, when I used it to get under a storage shed that I moved. Very sturdy and high quality
This is a great little jack. I like the compact size, and it appears to be well made. Packing was excellent (to the point of being difficult to unpack...) but there was no way these (I bought two) were getting damaged. On a side note, this seller (TEMCo) requires a signature for delivery which is a huge inconvenience to me - I probably would have ordered elsewhere had I known that up front.
Great jack, especially for the price. I've used it to move my 2000 lb milling machine and 3000 lb lathe several times without breaking a sweat.
Using on the wing of a heavy duty Landpride shredder. Great cylinder!
Great I got just what I ordered the are perfect and would buy again thanks for a great buy
great
Good value and it came with extra seals to do either style cylinders.
Fit my Rotary lift cylinders perfectly. The seal kit was identical to the OEM SEALS. No leaks after installation. Cost was much less that the OEM kits.
No seal kits, but works as well as I can tell. Using for a Lanco filter press where the old hydraulic cylinder died. Seals for that cylinder were $600!!! The new cylinder was a little under $2000! This with a steel bar strong enough for the load replaced it. The handle is an essential on these heavy hydraulic cylinders. Would be nice if it had somewhere to bolt it on to something on the bottom. EZ-Tool said you could weld it to something, but that voids the warranty. I'll update if anything goes wrong. I accidentally loaded a different HYDRAFORE cylinder at about ~2 degree angle and it leaked at 5,000 psi. I've taken better care to keep this one straight. Like the other review mentioned, they don't sell the seals, but for the labor it takes to replace the seals well, if this stays cheap, it's worth it just to buy another. Piston could have pitting, for all you know. It should last years if you use it carefully, as 10,000 psi and 100,000 lbs of force should be used carefully. I've only used it twice as of Aug 2018; I'll update if issues happen.
Perfect for leveling my 10' x 10' shed.
This machine is freaking awesome make life easy
Nice piece of equipment. Good price Would recommend it to anyone in need of a cylinder with a 12 stroke..
Good for the price
Worked perfectly
WORKED GREAT JUST AS STATED
Was told prior to purchasing this cylinder that parts are available to repair these cylinders by EZ-Tools USA. Now that I have bad seals and contact EZ-Tools I am told no seal kits are available. Would of made a difference what brand cylinder i purchased. Should be under warranty for a year but after that I guess you can buy another cylinder.
I bought this jack nearly a year ago, and I've used it to pickup my entire machine shop, one machine at a time to install decent leveling feet. I haven't had any problems with it, no leaks, no trouble lifting anything I've used it on. I highly recommend it to anyone in a machine shop environment looking to lift things just enough to use moving skates or leveling feet or the like. The only annoyance in the design of this jack is that the release valve is only on one side. You can swivel the pump to lift the jack so that you can pump it up from the same direction on both the left and right of a machine, but for one of those you have to get around behind to crack the valve. Minor, but in a tight spot it can be a bit of a burden. Keep that in mind as you set up for a job, but I don't think many other jacks have that feature either. Plus, you likely don't have as crowded a shop as I do, since I'm constrained to a fairly small basement...
Great jack for the money, did everything i needed it to do. Moved several machine in our little machine shop, up to 7400 pounds
I used this to move my 1959 Heidelberg Cylinder printing press. It lifted it up like nothing.
Works perfect!
It was everything I needed for pump replacement
easy to use
Bit expensive, but they are what you need for keg posts.
Saved by bacon already - lost an o ring on the gauge hose and this kit had one to fit.
Great little rebuild kit. I do wish it came with new springs.
perfect repair parts for my minn kota motor
everything fit perfectly
Perfect! Everything fit perfectly. It's like I have new pump. Excellent ship time!
Well made product and helps to keep the smell of liquids in. I use it as a wast container to clean My Spray Guns.. will buy again!
I'm a BMW Technician and I always recommend this kit. It is a well thought out group of parts that will make your Vanos rebuild a breeze! The quality meets my standards, and the price beats them!
Comes in handy - never know what random o-ring you are going to need. Probably have a near life time supply of them with this kit.
All in one kit. Nice good price
Works great.
Replaced O rings in my BM and no more air leaks - worked just fine.
I finally got around to installing this over the weekend. The kit contains everything you could possibly need to get your VANOS running like new again. I didn't have the "rattle" that others did, but did have some vibration when idling that has significantly improved since install! A couple tips about install: Replace your valve cover gasket at the same time. You've already done the hard work and it's cheap. You MUST have a solid vice and impact wrench to open the VANOS and install the anti-rattle rings. I used a friend's garage specifically because of this. Get a bunch of dishes/cups to organize your bolts because you'll have a ton of them by the time you get here. A drill to install/remove bolts will save you a lot of time and effort. Torque the valve cover gasket bolts properly or you'll regret it. This took me ~6 hrs total as I ran into some difficult to remove bolts and one very stubborn solenoid connection.
Arrived quickly even though not on prime- didn’t have to install gamma ring - so that was a plus - they should just make sure they are installed - so people don’t have to do extra step- good quality bucket - will by again.
Good quality. No more leaks in my Mercruiser out drive.
awesome product, wont use anything else
excellent! everything right on
Perfect kit for your save a dive bag.
Easy to install to your existing shower head. It has made such a difference in giving our dogs a bath. So much easier.
I like that everything came in one package and included the pin wheel bearings as well as the thick washers which can be hard to find. I did notice after ordering though that it can be cheaper to buy the items individually.
Honest ad worked for my needs
Exact fit
As described
I use these as replacement o-rings on the top posts of my ball lock liquid and gas posts. The silicone makes it much easier to put on and take off the ball lock connectors, when the kegs are cold. Also seals great! A no brainer!
Good kit, haven’t used all the seals yet but the ones I have fit perfectly.
Don't be afraid to re seal on of these yourself, nothing to it. Worked great with no problems.
Perfect fit and saving money by doing it myself. The pool company charged me $150+ every time my pump's seals wore out and started leaking. The breakdown was $44 for the Go Kit and $100-$115 in labor. I watched a Youtube video on how to replace the Go Kit on my pump and now I am taking my wife to dinner with the savings!!
