Description

Built for trailer hub maintenance and oil bath axle service, the trailer oil bath cap helps protect wheel-end components while maintaining a reliable seal for heavy-duty trailer hubs.

Designed as a direct replacement trailer axle oil cap, the assembly features a durable screw-in plastic design with a 3.475" outside diameter and includes a matching O-ring to help prevent oil leaks and contamination.

The oil bath hub cap includes a removable filler plug for quick lubricant inspection and servicing without removing the cap, making routine maintenance faster and more convenient.

Compatible with Dexter-style oil bath hubs, the cap replaces Dexter Part #21-88, includes a replacement filler plug for Part #46-32, and a matching O-ring replacing Part #10-163.

Commonly used on 9K and 10K trailer axles installed on equipment trailers, dump trailers, gooseneck trailers, flatbed trailers, commercial trailers, and other heavy-duty towing applications.
