Effective Sealant for Automotive Wheels

This oil bath seal works like a charm for my car's wheels. It keeps OIL in and water out. The seal is durable and long-lasting .However, it can be a bit pricey compared to other options in the market..

Pros
  • Durable and long-lasting
Cons
  • Requires regular maintenance to ensure proper function

The seller does not send national stamps!

seller claims national seals then send cheap timkin seals. I ordered 2 of these and sent them to my mechanic who installed them. They started leaking after about 200 miles when I found out they weren't really national seals.

Pros
  • Unified design provides greater structural integrity, easier installation and leading edge protection.
Cons
  • zero
