Double Lip Boat Trailer Grease Seal Kit — 1.50" ID x 2.33" OD — Pair
Two-piece marine trailer grease seal kit for compatible boat trailer hubs using a 1.50" spindle wear surface and 2.33" hub bore. Double lip design helps retain grease while adding extra protection against water intrusion during launch and retrieval.
Overview
This R&P curated grease seal kit includes two double lip trailer seals sized for hubs that require a 1.50" inner diameter and 2.33" outer diameter seal. This size is commonly used in select UFP-style marine trailer hub applications and cross-references with the Dexter K71-799-00 / formerly UFP 7024 seal kit family. For boat trailers, the correct seal is critical: it keeps bearing grease in the hub and helps keep water, salt, grit, and road contamination away from the inner bearing.
R&P Service Insight
Boat trailer seals live a harder life than standard utility trailer seals because the hub is routinely exposed to water during launching, loading, and retrieval.
- Measure First: Confirm a 1.50" spindle seal surface and a 2.33" hub bore before ordering.
- Replace When Repacking: Removing an old grease seal usually bends or damages the metal casing, so seals should generally be replaced when bearings are serviced.
- Install Square: A seal driven in crooked can leak immediately, even when the dimensions are correct.
R&P Knowledge Hub
Compatibility: Fits compatible trailer hubs requiring a 1.50" inner diameter seal and 2.33" outer diameter seal. Do not order by axle rating alone.
Vehicle / System Fit: Marine boat trailer hub and bearing service applications using the matching spindle wear surface and hub bore.
Installation Notes: Verify spindle surface condition before installation. Grooves, rust, or nicks where the seal rides can cause a new seal to fail quickly.
Performance Insight: The double lip design provides two sealing contact points, helping retain grease and improve water exclusion compared with basic single lip seal designs.
Brand & Fitment Note

Application Reference: UFP, Dexter, Texcom, and National numbers in this listing are used as compatibility and cross-reference references only where the measured seal size and application match.
What This Means: This listing is for an R&P supplied two-piece grease seal kit, not a guaranteed OEM-branded item unless specifically stated and verified on the product packaging.
Before Ordering: Verify the inner diameter, outer diameter, spindle seal surface, hub bore, axle/hub style, and current seal number before installation.
R&P Repair Insight
A leaking inner seal can throw grease onto the inside of the wheel, allow water into the hub, contaminate the bearing cavity, and shorten bearing life. On a marine trailer, that small seal is one of the most important parts of the running gear system.
- Hub Bore Check: Clean the back of the hub and confirm the seal seats tightly in a 2.33" bore.
- Spindle Check: Confirm the wear surface measures 1.50" and is smooth enough for the seal lip to ride against.
- Seal Lip Check: Grease the lips before sliding the hub back on so the seal does not run dry or flip during installation.
