Frequently Asked Questions

Will Rislone Hydraulic Seal work with all regular types of hydraulic fluids?
Yes, Rislone Hydraulic Stop Leak is compatible with all petroleum based, mineral oil, and synthetic fluids. Do not use with water-glycol or phosphate ester flame retardant hydraulic fluids. Do not use in brake fluid systems.
 
How does Hydraulic Seal work?
After time, hydraulic seals and o-rings tend to dry out and shrink. Rislone revitalizes these seals and o-rings and makes them soft and pliable again.
 
If first application does not completely stop leak, may I add another dosage?
Yes, you can install a second application for hard to stop leaks. If your leak still persists after a second application, then mechanical attention is needed, and replacement of seals may be required.

Can Hydraulic Seal be used for preventative maintenance to help prevent leaks?
Yes, this is a great product to use in older systems to keep them working properly not only to prevent leaks, but keep the system lubricated and protected. The recommended preventative maintenance dose is 15mL per liter of fluid capacity.
 
How long does it take to start working?
Rislone Hydraulic Seal starts working the minute you install and start using equipment. Most leaks are sealed within a few hours of application and usage. Some leaks can take longer, up to a few days. Old accumulation of fluid on outside of system may drip for a few days after leak has stopped.
 
My hydraulic system uses motor oil, can I still use Hydraulic Seal?
Yes, Hydraulic Seal will mix and work perfectly in a hydraulic system using motor oil.
 
Will Hydraulic Seal change the fluid viscosity?
No, we have designed the formulation using a multi-viscosity hydraulic fluid as a carrier which when used at the recommended dosage will not take ISO 22, ISO 32, ISO 46, ISO 68 or ISO 100 out of grade specification.
 
Will Hydraulic Seal harm painted surfaces?
No, this product will not affect painted surfaces any differently than straight hydraulic fluid.
 
Will Hydraulic Seal harm hoses?
No, this will not harm or affect hoses in any way.
 
What is the difference between hydraulic fluid and hydraulic oil?
Nothing, they are the same thing, just a terminology difference.

My Dog Loves this!
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves her Nubbies! My Dog chews her Nubbie every morning after she has her breakfast. She sometimes wants my husband or I to hold it for her while she chews on it. I think it is really good for her teeth and gums. These last a few months for our dog who chews it every morning. After a few months the edges get a little rough from all the chewing so I throw it out and replace with a new one. These are very reasonably priced, so I always have a fresh one ready to go. She gets very excited when we get a new one out of the package..

Pups like them
Size: 4 Inch (Pack of 2)
It took a little bit but once my dogs started chewing on them they seem to like them. They're holding up pretty well and not destroying them too quickly like they did some other chews.
