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

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!

What can I say, the smallest pair worked perfectly for my old Gehl 3310 tilt cylinder rebuild. After fighting with the one last seal that goes inside the cylinder and trying all the tricks on Y.T., I ordered these. It took, maybe 30 seconds, if that and it was in place. Quality seems to be good, I had no issues. I would buy again, and recommend these. They are a good investment having a 35 yr. old skid steer....lol

Helped incredibly with my first seal installation project. Would have been nice to have an option to buy just one though, as I've no need for three of these. Even if I never use the tool again, it served a vital role to get seals in quickly and efficiently.

Worked great !

These work well for difficult inner seals - durable and helped me with rebuilding hydraulics for my tractor!

Really simple to use

Very nice tool

These collapse seals wonderfully.

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.

Seal installer to small to use on my job.

Welds snapped on the third use for both the "medium" and "heavy" tool. Quality of steel is also questionable. You're better off making your own tools. At least they weren't expensive.

Tool broke first use.

first time i used tool weld broke
