3 Pack Hydraulic Seal Installation Tools, Hydraulic Cylinder Piston Repair Seal Kit, U-Cup Rod Seal Installation Tool Kits Upgraded Seal Twistor Install Tool Set

A good product that met my expectations. Arrived on time. Good communication.

Wanted a set like this for years but always made do, struggling and risking damaging the seals. I didn’t think it would be worth getting them. Glad I did. So easy to use and or course it’s the proper, professional way to install seal. Definitely recommend them.

Only used once so far. However, the internal rod seal I use it on was a bear! Took quite a bit of muscle on the next to the smallest seal tool to get the seal to fold enough so it would go in the bore of the gland. The tool took the strain just fine. I've installed many,many seals without these tools. It's doable. But having them now will make it easier.

I had the seals on my JD tractor loader cylinders start to leak, so I had to rebuild them... on the first one, it took me nearly an hour to get that darn internal seal in place and it was a total PITA. They say to bend it into a 'kidney' shape to get it in, but doing it by hand or trying to improvise a tool to do it was a nightmare. After that, I decided to order this set of tools to make things a bit easier. Boy did they! On the next rebuild, it took me maybe 1 minute to get that seal in place with no hassle or fuss at all. World of difference. It may be one of those tools that you only use rarely, but for the price, it's well worth it just to reduce the hassle factor of dealing with those seals. I read that some people got them with bad welds or had other problems. I didn't notice any of that - they were sturdy and did the job flawlessly. If you have to install similar interior seals, I highly recommend these to help reduce your hassle factor!

Sloppy, poor quality set of tools that aren't good for heavy duty hydraulic seals. I tried to use the largest pair (Red) to install a beefy Hallite seal in a 3.25" linear actuator. The fingers had no grip on a slick greasy seal & the retainer clips immediately went wonky after use. Cannot recommend.

I'm relatively new to this. I tried "making do" without these when working on my 35+ year old Kubota 4530B Backhoe that likely spent its entire life outdoors. It apparently had the original seals and was never torn apart. I ultimately had to drill out the holes to the 5/16" size pin on the first cylinder. I didn't have a 3/4" socket wrench, but made an adapter out of a spare short 1/2" drive extension by grinding 4 square sides on it. until it fit into this. That worked well enough to bust a breaker bar and max out my 250lb torque wrench... it wasn't budging, but the pins didn't break, either. I soaked it and left it for the night. The next morning I walked over to "old man that knows how to do everything" neighbor and borrowed his 3/4" inch socket and ask for any tips. He mentioned to bang around on the side of the cylinder, where the threads are, with a hammer a few times... and that you can use heat as a last resort. Well, I banged all around the side of the cylinder for a minute and got out the propane torch just to heat it up a bit. I put the new wrench on it and I don't think I applied more than 100 ft lbs of torque before it wound right out. The next cylinder was much easier, I guess since it wasn't directly exposed to the weather... I used the 1/4" pins and they worked just fine. Upon installing the seals, the install tool is so much nicer than trying to wedge them in with your fingers... so that was nice to have, too. Overall, I beat this thing a good bit, and it took it. I believe it was money well spent.
