MIA's Description
Constructed from 100% flexible graphite, these gaskets can withstand temperatures up to 3,000 degrees F and are designed to crush 50% to seal warped flanges. They are a direct fit for Husler Headers, AFR, Dart Heads, and other applications.
Installation guidelines recommend avoiding bending the gaskets, not overtightening, and not using sealers. Standard length bolts will work fine.
