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.
