Buying Guide: Key Purchase Considerations
- Seal size: Most 3,500 lb EZ-Lube axles and 5-lug hubs use a 1.719″ inner diameter and 2.565″ outer diameter. Always measure the existing seal’s ID and OD before buying.
- Lip design: Double-lip seals tend to offer better protection against water and debris than single-lip designs, especially for boat trailers exposed to spray.
- Material and construction: NBR rubber with steel springs provides durability and resistance to oil, salt, and temperature changes common in marine environments.
- Included hardware: Cotter pins simplify installation. Consider kits that include pins if you’re replacing multiple seals at once.
- Compatibility: Check your spindle type and part numbers (Dexter, Transcom, National, NOK, GS-2250DL, etc.) to ensure proper fit.
- Installation considerations: Misalignment or over-tightening can cause leaks or seal damage. Follow manufacturer guidance for press-fit or seating depth.
