WE ARE HERE TO HELP.

All orders and inquiries are reviewed by engineers. MAIN Manufacturing's weekly order review system discovers many customer typos, mismatched descriptions, mismatched parts, and other problems. This saves time, money, and embarrassment. MAIN's engineers sit on several SAE and NFPA committees, have been US experts to ISO committees, and are involved in writing the standards. These same people are available to help customers with a difficult connection or piping situation.
