SealLube is a special plasticizer that is safe and effective for all rubber seals. After adding SealLube, with the help of fluid circulation, it quickly soaks in and restores rubber seals to their original condition.

It is recommended to add 1 ounce per quart capacity.  For example: one 8 oz. bottle of SealLube will treat up to 8 quarts of fluid / oil.

Since every leak is different, every repair varies in time. If the SealLube is being added to vehicle or piece of equipment that is used every day or several times a week, it may only take 1 to 2 days.  However, if it’s being added to something that sits for months at a time you may need to start it 2 or 3 times a day for several days, even if it’s only a few minutes at a time.
