Hydraulic Stop Leak – 32 oz | Restores Seals & Stops Leaks in Hydraulic Systems | Safe for Pumps, Cylinders & Valves

I used this in a 256 versatile that had a bad hydraulic oil leak between the engine and hydrostatic transmission. After about a week the leak was about non existent. After a year has stopped completely. Great product. Will buy again and again. Great product.

Used a bottle in my tandem axle dump truck hydraulic system a month ago. Before the lift piston was leaking noticeably and making a mess, now it barely leaks anything, it's not a miracle "repair" in a bottle, but for the price you can easily squeeze in my case months more of use out of a badly leaking hydraulic piston to give you more time before paying that hefty repair bill. Wouldn't hesitate to buy again.

Stopped two leaks for me. I love this stuff. Had a forklift that had a puddle under it every morning - now there might be a drop after is sat for a week !

Seals on my wood splitter was leaking fluid. Used the while bottle. Slowed leak but didnt completely stop it. Lesk was a 9 now its a 2. So far...

The loader bucket on my Massey Ferguson was dropping fast to the point I couldn’t even use it after draining a couple quarts of hydraulic fluid I added a half bottle of this and filled it back up with new fluid every day I would start it put the throttle at operation speed and work the bucket up and down about 10 times then shut it down relieve all pressure using the control stick. Did this for 3 days the 4th day I was scooping full buckets of dirt it completely fixed it. Highly recommended

It helped right away but didn't stop completely , I'm happy to stop most of the leak

My utility tractor had developed several leaking cylinders over the past few years, some had become fairly heavy leaks!! I Added this product to my tractors hydraulic tank at the recommended amount for the system size, let the machine run for 10mins to warm up and mix, cycled all the hydraulic cylinders to full travel about 10 times each to ensure the additive got into each cylinder. I was hopeful that after using the tractor that day this product might help to slow the leaks down a little!! To my Complete Suprise in the 5 or less minutes it took me to get ready to get on the tractor to start the work I had planmed for it that day, the leaks had all but stopped, within 10 minutes of using the loader to move some dirt the leaks (ALL OF THEM) had stopped completely! That was nearly 4 months, and many hours of work ago and still no drips.

I highly recommend using this product before you pay hundreds of dollars to have your cylinder rebuilt. Awesome product.
