The LIQUI MOLY Gear-Oil Leak Stop is a specialised seal-conditioning additive designed to prevent and eliminate oil loss in manual transmissions, differentials and final drive units. Formulated to rejuvenate hardened or shrunken plastic and rubber seals, it stops drips and seepage, protects couplings from contamination and prevents lubrication shortages that may lead to costly component wear or failure. Compatible with all commercially available gear oils, it supports smoother operation, cleaner running and long-term gearbox reliability while helping prevent environmental pollution caused by leaking oil.
