National has earned a reputation as a trusted name in premium sealing solutions for more than 75 years. The National 370025A wheel seal is designed for Clark and Rockwell-Standard FWRW hubs, blending durable material with a precise design to support reliable operation in demanding conditions. This seal is built to withstand a wide temperature range and resist wear, making it a practical choice for maintenance or component refreshes.

Why choose the 370025A wheel seal

Key design choices focus on long-term durability and easy installation. The Dynamic Edge Red 37 Series oil bath seals provide a dependable point contact seal, helping maintain a solid seal over time.

  • Dynamic Edge Red 37 Series delivers dependable point contact sealing
  • Abrasion-protected nitrile with a spring-loaded main lip for positive sealing and reduced shaft interference
  • Unitized construction for greater structural integrity, easier installation, and main lip protection
  • Unique rubber inner and outer diameters with patented SURE-LOCK ribs that inhibit shaft leaks and protect bores
  • Wide temperature range from -40 F to 225 F (-40 C to 107 C) for varied climates and workloads

Fitment and compatibility

Compatibility is key. Before purchasing, check the Amazon Confirmed Fit bar to verify your vehicle's year, make, model, engine, and trim. If you see a blue i icon, hover to view notes before buying.

Real-world use and installation tips

The unitized design supports straightforward handling during installation and adds structural integrity in vibration-prone hubs. The nitrile compound offers abrasion resistance, helping the seal resist wear as part of routine hub maintenance. For best results, inspect the shaft and bore for damage and follow proper lubrication and installation guidelines.

  • May contribute to longer service life when used in correct applications
  • Spring-loaded lip maintains contact with the shaft across small irregularities
  • Protects bearing bores from leaks and wear during operation

National's wheel seal line demonstrates a balance of engineering and reliability, making it a practical option for professional technicians and fleet maintenance programs alike. This part is intended to support proper sealing in compatible Clark and Rockwell-Standard FWRW hubs without guaranteeing specific outcomes, as with any mechanical component.
