R&P P/N: OC-Rubber Plug-LOTOF2 2-Pack Fits 7/8" Center Hole
Overview
This R&P Carriages oil cap center plug set includes two replacement rubber plugs for compatible oil bath hub caps. The plugs fit a 7/8" center hole and are used as a replacement-style solution for Dexter 046-032-00 plug applications where the cap model, center opening, and plug configuration match.
R&P Service Insight
Oil bath hub caps rely on the center plug to help retain oil and protect the hub cavity from road contamination. A worn, loose, cracked, or missing plug can create a leak path and should be addressed during hub service.
- Seal Point: Installs in the center opening of compatible oil bath caps.
- Service Access: Maintains a removable center plug location for hub oil inspection and service.
- Inspection Item: Replace plugs that are brittle, cracked, swollen, missing, or no longer seat firmly.
R&P Knowledge Hub
Compatibility: Designed for compatible oil bath hub caps using a 7/8" rubber center plug opening.
Vehicle / System Fit: Oil bath hub cap systems found on many trailer axle and hub applications where the listed cap references and measurements match.
Installation Notes: Verify the existing cap model and measure the center plug opening before ordering. The replacement plug should seat firmly without being loose or forced.
Performance Insight: A properly fitted rubber center plug helps retain oil inside the cap while reducing exposure to dust, water, and road debris.

Application Reference: Dexter names and part numbers are used only to describe compatibility with listed oil cap applications.
What This Means: This listing is for an R&P Carriages 2-pack of replacement rubber oil cap center plugs, not a guaranteed OEM-branded Dexter item unless specifically stated and verified.

R&P Repair Insight
If oil is seeping around the center plug, inspect both the plug and the oil cap opening. A damaged plug, hardened rubber, incorrect plug size, or damaged cap can prevent a proper seal.
- Hole Size Check: Confirm the cap uses a 7/8" center plug opening.
- Cap Reference Check: Common compatible cap references include 21-35, 21-36, and 21-88 where the center plug size matches.
- Fit Check: The plug should sit securely in the cap opening before the trailer is returned to service.
