Four genuine USA-made Dexter unitized oil seals designed for 7,000 lb and 8,000 lb oil bath trailer axles. Includes four seals — enough for two axles.
These seals are commonly used in Dexter oil bath hub assemblies and are not interchangeable with grease-style hub seals.
R&P Knowledge Hub
A unitized oil seal is a dual-action assembly where the inner case remains fixed on the spindle while the outer case rotates with the hub. This design minimizes wear between sealing surfaces and improves oil retention in oil-bath hub systems.
7K and 8K axles may use different seal sizes depending on hub configuration. Always confirm inner diameter and outer diameter measurements before ordering.
