Material Notes:

GRAFOILÂ® GTJ premium flexible graphite is an oxidation/corrosion inhibited grade developed for use in nuclear and high temp, high purity applications. It is certified to meet the most rigorous purity specifications of the nuclear industry, including the General Electric Nuclear Nonmetallic Material Specification D50YP12 (Rev 2) and is typically 99.8% graphite. While maintaining an effective seal, GRAFOILÂ® material exhibits virtually no creep relaxation. As a result, the need for periodic bolt tightening is greatly reduced.
