iBroPrat Trailer Axle Grease Seal Kit 10-pack for 3,500 lb Axles — ID 1.719" × OD 2.565", NBR Double-Lip with Cotter Pins

iBroPrat 10pack Trailer Axle Grease Seal is a set of ten double-lip NBR rubber seals with matching cotter pins engineered to fit 3,500 lb axles and spindles (ID 1.719" × OD 2.565" × W 0.5").

These replacement axle seals come as a bulk kit—ten seals plus ten 2.25" cotter pins—designed to match common OEM part numbers (Dexter 010-019-00, Transcom 171255TB, National 473336, NOK AD2548EO, GS-2250DL). Built with a steel-reinforced casing and a double-lip NBR sealing surface, the seals resist oil and corrosion while keeping hub grease where it belongs. Each piece is bubble-wrapped to reduce transit damage and backed by a satisfaction replacement policy.

Will these seals fit my 3,500 lb trailer axle?

Measure the inner and outer diameters of your current seal to confirm fit: this kit is sized for an inside diameter of 1.719" and an outside diameter of 2.565" with a width of 0.5". The kit targets 3,500 lb axles and the corresponding spindle sizes.

• Exact seal dimensions: ID 1.719", OD 2.565", width 0.5".
• Includes ten seals to service multiple hubs or spares.
• Matches common OEM numbers for 3,500 lb applications.

How durable and leak-resistant are these seals?

These seals use NBR (nitrile) rubber with a steel case and a double-lip profile to deliver improved oil resistance and protection against contaminants. The reinforced design helps maintain a secure fit under typical towing loads and highway exposure.

• Double-lip design for improved grease and oil retention.
• Steel-reinforced casing reduces deformation during installation.
• NBR compound resists oil, grease, and common contaminants.

What comes in the package and how does it save me time and money?

You receive ten axle seals and ten 2.25" cotter pins, ready for multiple hub rebuilds or to keep as spares. Buying in this bulk pack lowers per-seal cost versus single retail purchases and saves trips to parts stores when you service several wheels.

• 10 seals + 10 cotter pins for multiple repairs or stock spares.
• Bubble-packed parts to reduce shipping damage and returns.
• Lower unit cost compared with single-seal purchases.

How should I install and check these seals for proper fit?

Clean the spindle and hub bore, inspect for wear, and gently press the seal squarely into the bore until flush; avoid prying or hammering on the lip. After installation, torque bearings and check for leaks during a short test tow.

• Inspect spindle and hub for grooves or corrosion before installing.
• Use a seal driver or socket sized to press the outer case evenly.
• Verify cotter pin fit and bearing preload after installation.

Who is this for: This 10-pack is aimed at trailer owners, fleet managers, and DIY mechanics who routinely maintain 3,500 lb axles or want economical spares. It’s especially useful for shops and owners who service multiple trailers, perform seasonal hub rebuilds, or prefer keeping replacement parts on hand to minimize downtime. If your current seal measures ID 1.719" × OD 2.565" and you use a 3,500 lb spindle, this kit provides a cost-effective, ready-to-install option with protective packing and a seller-backed replacement policy.
