AMERICAN furnishes a line of 54"-64" Lok-Ring fittings that meet the applicable requirements of AWWA C110 or C153, depending on diameter and configuration. These fittings employ the standard Fastite seal, and the joints meet the applicable requirements of AWWA C111. Many of these fittings are not specifically listed in the AWWA standards because of joints, outlets or other variations, and as such are designated as “AMERICAN Standard.”
Lok-Ring fittings are furnished of only ductile iron. They are furnished complete with standard Fastite plain rubber gaskets and a sufficient supply of Fastite joint lubricant.
Lok-Ring fittings are normally furnished with standard cement lining in accordance with AWWA C104 and with a standard asphaltic coating on the outside. For special conditions, other types of coatings and linings may be available.
