Blue Label seals are superior because they are made using a high material grade, proprietary compound. This is obvious because the seals:
1) Produce and maintain less friction and virtually no stick-slip
2) Seal better and last longer
3) Have better weathering resistance
4) Are compatible with many OE and aftermarket oils
5) They even look better
The seals are made, 100% tested and packaged in our specialized facilities, meaning that you can rely on the quality of each and every seal.
