It revitalizes rubber seals by restoring their original flexibility and strength, working within hours and providing lasting protection. Compatible with all fluid types except brake systems, SealLube is a trusted solution to prevent leaks and extend the life of your vehicle’s critical components. ## Description SealLube Positively Stops Existing Leaks In Any Fluid System: Gasoline engines, diesel engines, marine engines, farm tractors, hydraulic systems, manual transmissions, automatic transmissions, power steering units, rack and pinion, jacks, heavy equipment, differentials, refillable shock absorbers, gear cases, I/O drives, PTO valves and air conditioners. Do not use in brake systems. The SealLube formula quickly revitalizes hard, shrunken, leaking rubber seals to original condition and prolongs the life of all seals to prevent future leaks. SealLube added to any system will prevent future leaks by conditioning even new seals. Does not work on paper or cork. Compatible with all manufacturers’ fluids, both conventional and synthetic. DIRECTIONS: 1. With engine or equipment not operating, add 1 oz. of SealLube per quart capacity to fluid reservoir, crankcase, or oil sump (one 8 oz. bottle treats up to 8 quarts). 2. Start engine and drive vehicle or operate equipment as normal. The SealLube formula quickly revitalizes hard, shrunken, leaking rubber seals to like new condition as the fluid circulates. Since SealLube does not contain petroleum distillates, which can destroy seals after temporarily expanding them, it is safe to repeat the treatment if the seal/system ever leaks in the future. ## Features - Stops Leaks: Gasoline Engines, Diesel Engines, Hydraulic Systems, Transmissions, Power Steering Units, Rack and Pinion, Differentials, A/C and much more! - Restores flexibility, elasticity and tensile strength of all rubber seals - Seals Leaks: Transmissions, power steering, main bearing, jacks & hydraulic systems - Works in Hours - Lasts for Years ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079SN84J1 | | Best Sellers Rank | #36,578 in Automotive ( See Top 100 in Automotive ) #60 in Engine & Oil Fluid Additives | | Brand | SealLube | | Customer Reviews | 4.3 4.3 out of 5 stars (844) | | Date First Available | February 13, 2018 | | Item Weight | 1 pounds | | Manufacturer | NEW TECH INTERNATIONAL | | Manufacturer Part Number | 4008 | | Package Dimensions | 6 x 4 x 4 inches | ## Images ![Stops Leaks: Gasoline Engines, Diesel Engines, Automatic Transmissions, Manual Transmissions, Power Steering, Rack and Pinion, Differentials and Hydraulic Systems - 8 oz. - Image 1](https://m.media-amazon.com/images/I/71syXMF5V2L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Hello, im not sure if this is a prohibited item?. in dominican customs (final destination). quimics, corrosive, are good if good package...** A: it expands rubber,I don't see any customs problem,I'm not a lawyer.... **Q: Will it work on a motorcycle that has a wet clutch?** A: As a matter of fact I used it in my clutch on a manual Corolla, and it actually helped quite a bit. **Q: Will this expand viton rubber o-rings** A: I’m not certain what types of rubber.
