Products - Tri-Seal (Pack of 2)

Hapco Tri-Seal positively stops leaks in all engines, transmissions and power steering units. This exclusive formula revitalizes the flexibility, elasticity and tensile strength of rubber seals to original condition and also helps prolong the life of all seals to prevent future leaks. Does not contain petroleum distillates, which can harm or destroy seals, and is 100% non-clogging. Tri-Seal is compatible with all manufacturers’ fluids and has a proven history of success since 1960. FOR BEST RESULTS: With engine off, add one bottle of Tri-Seal to the engine, transmission or power steering fluid reservoir at any time (or 2 oz. per quart capacity). Drive vehicle as normal to allow circulation of fluids. Most leaks are repaired in as little as 2 hours of total fluid circulation (or 1-2 days of normal driving). After the leak is repaired, Tri-Seal can remain in the system until mileage indicates need for oil / fluid change. Tri-Seal is also safe to use in: hydraulic systems (jacks / cylinders / pumps), marine engines, differentials, rear axles, refillable shock absorbers, gear cases, reduction gears, transfer cases and pillow blocks.
