The MTR is a material (or mill) test report and quality assurance document. Used in the metals industry, it certifies a material’s chemical analysis and physical properties. We currently offer MTRs for our biopharm fittings used in the pharmaceutical, food processing, and personal care markets, and for our vacuum fittings used in the semiconductor market. The heat trace (job) number can be found on the package or laser-etched on the fitting. Enter that number in the box below to retrieve a copy of the MTR.
