Anti-Leak Gear Oil, commonly known as Bel-Ray® Anti-Leak Gear Oil, offers superior leak suppressing capabilities resulting from a unique gelling system. When the gears stop rotating, Anti-Leak Gear Oil gradually forms a weak gel, reducing the lubricant’s fluidity and tendency to bypass faulty seals. When the gears begin to spin and the lubricant is exposed to mechanical shear, Anti-Leak Gear Oil becomes more fluid in the area immediately surrounding the spinning gears while the bulk of the lubricant remains gelled, eliminating the tendency to leak. This property continues to cycle from gel to fluid to gel, effectively reducing or eliminating oil leakage. Anti-Leak Gear Oil seals the lubricant in while sealing contamination out.
