4Pcs Trailer Axle Hub Wheel Grease Seals

Best for replacement on Dexter 010-019-00 (10-19) hubs and EZ-Lube axles in 3,500 lb trailers. These double-lip grease seals are sized ID 1.719″ x OD 2.565″ and include cotter pins. They fit many 5-lug hubs, providing reliable sealing against water and dirt ingress. Choose this if your trailer uses Dexter or similar hubs and you want a direct-fit option.
Best-for usage notes: Confirm the inner/outer dimensions of your current seals before buying. The kit includes four grease seals and cotter pins, simplifying a one-kit replacement for a full axle set. A potential limitation is if your hub uses a non-standard spindle size, in which case this may not seal properly.
GREPSPUD 20pcs Trailer Hub Rubber Grease Plugs

Best for bulk replacements and on-the-go maintenance for 2,000–3,500 lb trailer axles. The 20-piece value pack covers EZ-Lube caps and dust plugs, with a size compatible for typical dust cap holes. This set is ideal for fleet owners or frequent DIYers who want ready-to-use plugs and quick swaps when seals or caps wear out. A limitation is potential mismatch if your dust cap size differs from the listed 1.17″ I.D. hole.
RV Murts Double Lip Grease Seals

Best for sealing durability on 2,000–2,200 lb trailer axles with double-lip design. Made with mild steel and NBR rubber, these seals emphasize resistance to pollutants and temperature variation. They are suitable where steady sealing performance across a range of temperatures matters most. A caution: verify compatibility with your specific spindle model and ensure correct ID/OD match to avoid leakage.
OZISENS 4pcs ID 1.719″ x OD 2.565″

Best for replacement on 3,500 lb EZ-Lube hubs using #84 spindles. The seals match ID 1.719″ x OD 2.565″ and include cotter pins. They’re suitable for Dexter 010-019-00 and other common hub numbers, offering a direct fit for standard Dexter and Transcom hubs. A limitation is potential incompatibility with non-standard hub configurations requiring different seal dimensions.
Lippert 333953 Double Lip Grease Seal

Best for universal fit across multiple trailer axles (1250–8000 lb) with various hub brands, including Lippert, Dexter, and Al-Ko. Available in several sizes, this double-lip design offers a protective barrier against elements and a broad replacement option when upgrading or standardizing parts across a mixed fleet. Choose this if you want broad compatibility, but ensure you pick the exact size variant for your spindle and hub.
Buying Guide
What size seal do I need? Measure the inner diameter (ID) and outer diameter (OD) of your current seal and match the closest ID/OD. Check spindle compatibility (e.g., 1.719″ ID x 2.565″ OD or 1.249″ ID x 1.983″ OD) and ensure EZ-Lube compatibility if applicable.
What type of lip design should I choose? Double-lip seals offer better protection against water and dust, especially in wet marine environments. If you have higher temperature exposure or heavy use, look for materials like NBR rubber with steel construction for durability.
Should I buy in bulk? Bulk packs are cost-efficient for frequent maintenance or fleets. However, confirm the exact seal size and cotter pin compatibility since some sets include different cotter pin lengths (e.g., 2.3″–2.4″).
What brands should I consider? Reputable brands like Lippert, Dexter, and Al-Ko ecosystems are more likely to maintain consistent sizes across models. For mixed fleets, a universal-size option within Lippert/Dexter-compatible variants can simplify replacements.
