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.
Fittings are generally per AWWA C153. While AWWA C153 shows 54"-64" fittings with 150 psi ratings, AMERICAN rates many 54"-64" fittings 250 psi as AMERICAN Standard based on performance testing.
Fittings can be furnished on the runs with Lok-Ring ends.
Crosses with smaller reductions may be available; however, welded-on outlets are normally preferable in these cases from a layout, lead time, installation and economical standpoint.
