AMERICAN furnishes a line of 4"-48" Flex-Ring fittings that meets the applicable requirements of AWWA C110 or C153, depending on diameter and configuration. These fittings employ the standard Fastite or Fast-Grip gasket seal, and the joints meet the applicable requirements of AWWA C111. Some 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.”
Flex-Ring fittings are boltless and use the Fastite gasket for joint sealing.
Flex-Ring fittings are furnished of only ductile iron. They are normally furnished complete with Fastite plain rubber gaskets and a sufficient supply of Fastite joint lubricant.
Flex-Ring fittings are normally furnished with cement lining in accordance with AWWA C104 and with a standard asphaltic coating on the outside 1. For special conditions, other types of coatings and linings may be available.
1.) 4" – 12" Flex-Ring fittings are provided with zinc-rich primer and top coat on the exterior and are typically an 8-week lead time for delivery.
Reducers may be available with Flex-Ring or Lok-Ring bells and Flex-Ring or Lok-Ring ends. The dimensions shown here are representative of bell-configured reducers for Flex-Ring and Lok-Ring. As such, some variation may occur. Consult AMERICAN for exact dimensions (including laying lengths in some cases) and weights if these are critical.
Plain ends on available reducers may or may not be beveled/smoothed for push-on joint assembly. If push-on assembly is required, such ends may require field bevel/smoothing. Also see Plain End.
