A flow limiter component including a monocoque body having first, second, and third sections along a longitudinal axis. The first section includes a first end defining a first edge of the monocoque body and a bordering second end, and a first inner diameter defining a first chamber inside the first section. The second section includes a solid wall, with an orifice disposed therein, in fluid communication with the first chamber, the orifice defined by a second inner diameter. The third section includes a third end bordering the second section and a fourth end defining a second edge of the body, and a third inner diameter, the third inner diameter defining a second chamber in the third section. The second chamber is in fluid communication with the orifice. The first inner diameter is greater than the third inner diameter, and the third inner diameter is greater than the second inner diameter.
