&#60;p&#62;&#60;strong&#62;Manganese Phosphating Anti-Gall Treatment&#60;/strong&#62;&#60;/p&#62;&#13;&#10;&#13;&#10;&#60;p&#62;Manganese Phosphate Treatment on re-machined and new Rotary Connections prevents galling to the shoulder seal and thread surfaces on initial make-up. This is because the phosphate coating acts as a barrier and physically separates the metal surfaces during initial make-up.&#60;/p&#62;&#13;&#10;&#13;&#10;&#60;p&#62;Also, the phosphate process etches microscopic pores in the metal surface which retain the thread dope to provide lubrication between the metal surfaces when high torque loads are applied.&#60;/p&#62;&#13;&#10;
