5.0 out of 5 stars Works great for slow leaks.
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!

This stuff has worked every time I have used it. Worst case was a hitachi zx350 that poured hydraulic oil from main valve body. I used 4 gallons in that machine before it finally stopped leaking. Most other times 2 quarts and a week or two and it’s not leaking anymore. It won’t fix broken parts!
4.0 out of 5 stars Seal What?
Hello, I put the sealer in two different hydraulic tanks. It worked pretty good, I still have a small leak. I am buying another bottle because I faith it is going to work. The leaking cylinders are doing better. Thanks

This product stopped a hydraulic leak on my tractor in less than an hour. It's great when you find a product that does what it says it does.

3.0 out of 5 stars still leaking
not sure how long it takes to seal but after several hours of running still leaking.
5.0 out of 5 stars This stuff really works!
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.
Good product
Fast delivery and god quality product.
Pretty sure it works. I'm just not sure how well yet.
I like the container and its contents. More than enough product for the job I had for it. I knew of an obvious seal leak in a hydraulic ram on my tractor. Being an old girl and myself being new to this fairly complicated machine, I'm not sure just how many internal leaks she may have had or how many have been repaired. So far nothing bad has come of any of it so I give it a thumbs up. 👍
Did not work
Used 2 bottles for my leaking hydraulic system. After 2 weeks, dipstick showed same oil level drop as before the Blue devil additive. Snake oil product.
