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.

Great for heavy duty chewers
Flavor Name: Steak, Size: Medium
Our two dogs love these bones. They’re very durable for heavy duty chewers and it takes them a fairly good time to get through them. They must love the taste because it’s the bone they first pick up. I’ve gotten two flavors so far, beef and the peanut butter. Our dogs love them and because of that so do we.

Seems great, but not for my lab
Flavor Name: Bacon, Size: Medium, Flavor Name: Bacon, Size: Medium
I am rating this, to some degree, from a hypothetical standpoint. It SEEMS like a great bone. It SEEMS like it will last quite a while and withstand some avid chewers. However, I can't say for certain because it just wasn't well-loved by my Black Lab. She has a penchant for chewing animal bones. She loves to find wildlife bones in our yard and munch on them, so we do our best to provide healthy chewing options in the house. She will go to town on a cow's joint and even enjoys a peanut butter filled Kong from time to time, but this bone just didn't meet her expectations. It's not a bad bone. It has a very rugged feel and seems like it would be safe if bits and pieces were to begin coming off, like they're safely edible. I guess (and I can't say for sure..) it just doesn't have as much of a meaty flavor as many dog's like. If your pup is a Nylabone chewer- or likes to chow down on your loafers- this bone may be a perfect new addition to his/her toy bin.

Bone for destroyers
Flavor Name: Bacon, Size: Small
4 months ago I Bought this bone for my 90lb lab who destroys all his bones, but not this one! It barely has any teeth/chew marks on it and it’s one of his favorites. It was a great find and I’ll be sure to buy again. If you have a dog that destroys bones I’d give this one a try.

Immediate Doggy Happiness!
Flavor Name: Bacon, Size: Medium
Great dog bones! These are a nice size for my 55-pound Aussie, as well as our 96-pound Alaskan Shepherd. They are big enough to last for a while, and big enough to see so that I don't step on them with my bare feet; part of this is that they stick up off the floor a bit, instead of being a flat bone, all in one plane.
