Pair — Genuine Dexter 2.875" x 3.880" Unitized Oil Seals – 9K–10K General Duty
Genuine Dexter unitized oil seals designed for 9,000 lb and 10,000 lb General Duty axle hubs using 12.25" x 3.375" brake drums. Sold as a pair — enough for one axle.
Replaces Dexter part numbers 010-051-02 and 010-051-00. This updated design provides improved internal clearance to reduce potential bearing contact caused by tolerance variations within the hub.
R&P Knowledge Hub
A unitized oil seal is a dual-action design where the inner case remains fixed on the spindle and the outer case rotates with the hub. This configuration reduces wear between sealing surfaces and provides improved leak control in oil-bath hub systems.
Commonly used in Dexter 10K General Duty hubs with casting numbers such as 9-44, 8-415, and 9-123. Always verify seal inner and outer diameters before installation.
