What is CSST?
CSST is used to transmit gas in residential, commercial and industrial structures. CSST consists of a continuous, flexible, stainless steel pipe, and typically is covered with a yellow exterior plastic coating. In the case of one of the products manufactured by OmegaFlex, called “COUNTERSTRIKE,” the product is covered with a black exterior coating with yellow lettering. CSST typically is routed beneath, through and alongside floor joists, inside interior wall cavities and on top of ceiling joists in attic space from a gas source to an appliance. CSST does not include gas-appliance connectors (e.g.,a connector that runs from a gas outlet to an appliance).
There are four manufacturers listed in the lawsuit.
