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!

The Tool worked perfectly. Seal installment was done with in 3minutes.

Worked great !

Much needed basic tool good quality and fair price

Makes inserting a stiff hydraulic rod seal into the gland easy. I wish that I had these tools years ago.

Made rebuilding my hydraulic cylinder easy. Good product.

Really indispensable! Just got through replacing inner seals on some cylinder glands... these tools make quick work of 'compresssing' seals small enough to fit inside!

One of the new wonders that is really a big time saver .
