UFP Vault / Trailer Buddy Seal Service Kit
UFP Vault Trailer Axle Seal Kit – 2 Seals + 2 Stainless Wear Sleeves + 2 O-Rings
Part Number: 2x32123+2x33517U
A complete service kit for UFP Vault and Trailer Buddy style trailer axle setups using 32123 grease seals and 33517U stainless wear sleeves.
Includes 2 Seals Includes 2 Stainless Sleeves Marine Trailer Use
Overview
This kit includes two trailer axle grease seals, two stainless steel wear sleeves, and two O-rings designed for use with UFP Vault and Trailer Buddy systems. These components are commonly used on boat trailers and other applications where the hub seal rides against a durable, consistent sealing surface.

The double lip seal design helps retain lubrication inside the hub while helping keep water and debris out. The stainless wear sleeve provides a smooth sealing surface on the spindle, especially helpful when the original spindle surface has wear marks where the seal rides.
R&P Service Insight
When servicing Vault or Trailer Buddy style hubs, the seal and the surface it rides on should be checked together.
  • Seal Surface: A worn spindle surface can cause a new seal to leak prematurely.
  • Wear Sleeve: Stainless sleeves help restore a clean sealing surface.
  • Before Install: Confirm seal dimensions, spindle size, and hub style before ordering.
R&P Knowledge Hub
Seal Function: Grease seals retain lubrication inside the hub while helping prevent water, road grit, and debris from entering the bearing area.
Marine Trailer Use: Boat trailers place extra demand on hub seals because of repeated water exposure and ramp use.
Wear Sleeve Purpose: Wear grooves can form on the spindle where the seal rides. A stainless wear sleeve restores that sealing surface so the seal has a smooth, consistent contact area.
Fitment Reminder: Confirm the spindle size, seal inner diameter, seal outer diameter, and part numbers before installation.
Brand & Fitment Note

Application Reference: UFP Vault and Trailer Buddy axle hub systems using 32123 seals and 33517U stainless wear sleeves.
What This Listing Includes: Two double lip seals, two stainless wear sleeves, and two O-rings.
Before Ordering: Match by part number and measurement. Trailer manufacturers may use different hub, spindle, and seal combinations across similar trailer models.
R&P Repair Insight
A leaking hub seal is not always caused by the rubber seal alone. If the spindle surface has a groove, rust, pitting, or roughness where the seal rides, the new seal may not hold properly. Replacing the seal and sleeve together helps improve the chance of a clean, lasting repair.
  • Check the Spindle: Look for grooves, corrosion, or scoring at the seal contact area.
  • Check the Hub Bore: Make sure the seal seats squarely and securely in the hub.
  • Check the System: Verify the hub is compatible with UFP Vault or Trailer Buddy style components before installation.
