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 a 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.

No.  SealLube works while you drive or as machinery is operated!

No.  After the leak is repaired, SealLube will dissipate on it’s own.

Permanently! SealLube is a clear liquid with absolutely no particulate matter (which can potentially clog the system) and does not contain any petroleum distillates which can harm or destroy rubber seals after temporarily expanding them.

Yes.  Rubber seals often shrink and lose their flexibility due to heat, age and wear. Adding SealLube helps condition and revitalize all rubber seals, therefore preventing them from leaking.

Yes. SealLube is compatible with all types of  fluid / oil and will work even if other additives have already been added.


No.  It is not formulated to work for cooling system leaks.

Farm tractors, heavy equipment, hydraulic pumps, jacks, diesel engines, marine engines, differentials, refillable shock absorbers, gear cases, trim tabs, I/O drives, air conditioner O-rings,  PTO valves and much more!


Yes! Every bottle has been guaranteed to work since 1962.


SlipLube is a super slippery, super tough extreme pressure lubricant that is capable of clinging to the high end of fluid systems. It’s impervious to moisture, foaming, heat and pressure, which allows engines to operate cooler, quieter and longer!

This Friction Fighting Formula reduces operating temperatures, increases oil pressure and provides constant lubrication. This combination not only extends an engine’s life, but can increase gas mileage up to 20%.

16 oz. of SlipLube treats 4 to 6 quarts of oil.

Yes.  SlipLube is compatible with all types of conventional and synthetic oil.

The effects of SlipLube can last up to 4 oil changes. However, it is recommended to add at every oil change.

For best results, it is recommended to add every oil change. Do not overfill.

Yes. SlipLube keeps all rubber, leather, rope and cork seals positively lubricated, therefore protecting them from becoming hard, shrunken or worn.

No.  It does not contain graphite, teflon, PTFE resin or petroleum distillates.


SlipLube can be added to most power assisted hydraulic systems, including: Tractors, farm equipment, turbo engines, marine engines, motorcycles, snowmobiles, manual transmissions, power steering units and heavy equipment.

It is recommended to add 3 oz. of SlipLube per quart capacity.

No. This product should never be used in automatic transmissions.
