JE Pistons Pro Seal EJ25 EJ257 100mm 0.039in Single Headgasket Subaru 2006-2014 WRX / 2004-2021 STI

Every JE Pro Seal Head gasket utilizes the best raw materials available such as AISI 304 Stainless Steel. State of the art processes such as in-line laser cutting and multi-stage embossing technologies are utilized to ensure the highest level of quality available. In addition, every layer of our Multi-Layered Steel gaskets is invididually cut and formed to optimize performance.

Proprietary Coating Technologies: Multiple layers are used to provide the ultimate seal between the head and block mating surfaces. These coatings will normally eliminate the need for additional deck surfacing. Our coating processing provides 100% encapsulation of all exposed metal, far superior to other products that leave exposed raw steel on the edges. The layers include fluoroelastomer (FKM) for extreme temperature and chemical resistance. This technology provides superior conformability, oxidation resistance, and better removal, even after extreme temperature exposure.
