As a direct OEM replacement, this cap is manufactured to the same specifications as the original component, ensuring a proper seal and correct fit on your E-Z Lube hub assembly.

DHS Equipment stocks this genuine Multiquip part so you can get your trailer back in service without delay.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to original equipment specifications, this grease cap delivers the same compression fit and corrosion resistance as the factory-installed component, keeping contaminants out of the E-Z Lube hub.
• Direct Hub Replacement — Designed to press or thread directly onto E-Z Lube-equipped trailer hubs with no adaptation needed, maintaining the sealed grease path the system depends on.
• Broad Trailer Fitment — Compatible with Multiquip trailer models TRLR45H, TRLR45E, TRLR502XFH, TRLR502XFE, TRLRSG1600XFH, and TRLRSG1600XFE.
• Protects Wheel Bearing Life — A properly seated grease cap retains lubricant in the hub and blocks road debris and moisture, directly extending bearing service life and preventing premature wheel bearing failure.
• Safety-Critical Fit — A missing or damaged grease cap on a trailer hub can lead to bearing dry-out and wheel failure under load; using the correct OEM part ensures the hub remains properly sealed during towing.

The grease cap for the E-Z Lube hub system covers the outer end of the wheel hub, sealing in the grease that lubricates the wheel bearings. The E-Z Lube design allows grease to be injected through a fitting and pushed outward through the bearing assembly, and the cap keeps that grease contained while preventing water, dirt, and road debris from entering. When the cap is cracked, missing, or no longer seated correctly, grease escapes and contaminants enter — accelerating bearing wear and creating a risk of wheel failure during towing.
