OZISENS Trailer Hub Grease Seals 10-Pack — ID 1.719" OD 2.565", NBR Double-Lip with Cotter Pins

OZISENS 010-019-00 trailer hub grease seal kit includes ten high-quality NBR double-lip seals (ID 1.719" × OD 2.565") plus ten 2.3" cotter pins for reliable axle protection.

If you maintain 3,500 lb 5-lug trailer hubs, EZ-lube axles, or #84 spindles, this 10-pack replacement set simplifies routine service and emergency repairs. The seals are built from durable NBR rubber with an integrated spring and steel reinforcement to keep grease in and contaminants out. Supplied cotter pins let you finish multiple axle jobs without hunting for small hardware.

Will these seals fit my trailer hub or spindle?

Confirm fit by measuring the inner and outer diameters of your existing seal. This kit is sized at ID 1.719" and OD 2.565" and is compatible with many 3,500 lb 5-lug hubs, EZ-Lube axles, and #84 spindles. It is marketed as compatible with Dexter part 010-019-00 and similar cross-reference numbers.

• Check old seal dimensions (ID 1.719" × OD 2.565").
• Common cross references: Dexter 010-019-00, Transcom 171255TB, National 473336.
• Designed for 3,500 lb, 5-lug hub assemblies and EZ-Lube style axles.

How does the design reduce leaks and contamination?

The seal combines NBR rubber with a tensioned spring and steel support to form a dual-lip barrier that resists water intrusion and holds lubricant in place. The reinforced construction keeps sealing pressure even under vibration and temperature swings, lowering the chance of grease escape and bearing contamination.

• Double-lip profile for primary and secondary sealing surfaces.
• Internal spring maintains contact pressure over time.
• Steel-reinforced case resists deformation during installation.

What comes in the package and how many repairs will it cover?

Each kit contains ten seals and ten cotter pins, providing parts for multiple wheel hubs or for stocking spares. The included cotter pins are 2.3" long to match common spindle applications, letting you complete reinstallations without extra trips to the hardware store.

• 10 grease seals (ID 1.719" × OD 2.565").
• 10 cotter pins, each 2.3" length.
• Enough components for several axle services or full-trailer maintenance.

How should I install and care for these replacement seals?

Install seals cleanly using a driver that applies even pressure to the outer metal case; avoid pressing on the rubber lip to prevent distortion. Lubricate the sealing lip with fresh grease before fitment and inspect bearings and races for wear—replacing seals on damaged surfaces will not stop leaks.

• Seat seal by driving on the outer case evenly; do not hammer the lip.
• Pre-lube seal lips with compatible wheel bearing grease.
• Inspect hub bearings and races; replace damaged parts prior to sealing.

Who is this for: This 10-pack from OZISENS is ideal for trailer owners, fleet managers, and DIY mechanics who service 3,500 lb, 5-lug hubs or EZ-Lube axles and need a reliable supply of replacement seals and cotter pins. It suits routine maintenance, full-hub rebuilds, or keeping spare parts on hand for roadside repairs. If you’re unsure about fitment, measure your existing seal’s ID and OD and compare to the kit’s 1.719" × 2.565" dimensions before ordering.
