A double-primary-lip oil seal is designed specifically to separate media. Unlike the common primary-lip-plus-dust-lip arrangement, its two primary sealing lips completely isolate two different media, such as two liquids.

Applications:Transmissions; gearboxes, drivetrain components, and axles in agricultural or construction machinery

Sealing media:ATF, hydraulic oil, gear oil, and similar media

Lip materials:

NBR (-40°C to 120°C)
FKM (-20°C to 200°C)

Surface speed:NBR ≤ 8 m/s
FKM ≤ 15 m/s

Pressure:Max. 0.3 bar
