Which vehicles does this seal fit?

How is the seal constructed and what does that mean for reliability?

National designed the 710568 as a spring‑loaded, multi‑lip seal to maintain consistent contact with the shaft and resist leakage under varying conditions. The multi‑lip architecture provides sequential barriers against contaminants while the spring keeps the primary lip pressed firmly against the shaft.

• Spring-loaded design maintains lip tension over time
• Multi-lip profile offers staged protection from dirt and fluid loss
• Materials selected for low swell in hydrocarbon fluids
• Protection compatible with EP lubricants commonly used in axles

What temperature and fluid conditions can this seal handle?

The 710568 is rated to operate across a broad temperature span and is formulated to resist degradation in contact with lubricants typical of axle assemblies. These properties help preserve sealing performance in everyday driving and heavier-duty tasks.

• Temperature range: -20°F to 300°F (-29°C to 49°C) as specified by the manufacturer
• Low swell when exposed to hydrocarbon-based fluids
• Designed to be compatible with extreme-pressure (EP) lubricants
• Intended for routine and heavy-duty axle service environments

How do I be sure this part is the right choice for my repair?

Before purchase, compare the part to the old seal and use the seller’s confirmed-fit tool to check vehicle compatibility. If the compatibility checker shows an information icon, review the notes to confirm any special fitment details.

• Check the vehicle year, make, model, engine and trim against compatibility notes
• Compare physical dimensions and design to the worn seal you're replacing
• Review any seller notes shown by the compatibility tool before buying
• Choose seals from trusted brands like National for OE-style replacement
