      • Our NPT Malleable Black Iron fittings are made with care and attention to detail. Reduced parting lines and smoother edges result in better fluid flow. By using a low temperature galvanizing process the coating is more durable which means a longer lasting fitting. All Fittings are 100% Pressure Tested to 300# Class.

      • Material - ASTM A 197 - Cuppla Malleable Iron.
      • Pressure - Saturated steam: 150 PSI @ 350°F & Max pressure 300 PSI @ 150°F
