Abstract: A fluid flow restrictor device for controlling fluid flow at a connection between ducts may include a restrictor device body that is partially or fully inserted into and disposed within one of the ducts and an outboard restrictor device flange extending radially outward at an outboard end of the restrictor device body and having an outboard flange outer diameter that is greater than an inner diameter of the ducts so that the restrictor device body or the outboard restrictor device flange is engaged by an open end surface of the duct to prevent full insertion of the fluid flow restrictor device into the duct. A body inner surface defines a restrictor opening through the restrictor device body that can be varied to achieve desired fluid flow characteristics at the connection.
