BlueDevil Products 00239 Hydraulic Stop Leak - 1 Quart

Had a slow leak on my snow plow. Put just a little bit of this in and ran the hydraulics for about five minutes to work it in and I use the plow every day with no leak.

I have bought many products claiming to seal leaks. But rarely did they work.This product worked as advertised. It sealed a pretty bad leak on my hydraulic cylinder. Saved me a lot!

I first used this product to stop my engine oil from leaking. It worked! I used to stop at the gas station to check my gas and fill up my oil. That worked so well that I tried the product to stop leaks in the hydraulic system on my backhoe. Worked great! Probably saved $1,200. This stuff is great.

My 51 year old terramite backhoe showed significant leak stoppage.

Excellent for use in any vehicle

Product probably works ok, but one of the bottles was damaged and some of the product leaked out. Amazon won’t replace without returning the damaged bottle, which is too much trouble since I’m 20 miles away from a return center. So, my loss, I guess.

I was looking at a $2,000 replacement and thought I might as well try it. Added the fluid and ran it up and down about a dozen times every day. After three days the leak was definitely minimal and after a week no leaks at all. Will definitely use it again

i added this to my tractor hydraulic system to stop leaks in my front end loader. it worked ok for about two weeks. then the leaks got bigger and bigger. the my popwer steering ssystem totally failed after i added a litle to stop a small leak on it. the stuff totally plugged up the internal filter in the pump.. having to buy a new pump.
