a mix chamber disposed at least partially within a bore disposed in the plural component sprayer extending along a spray axis of the plural component sprayer and, the mix chamber comprising:
a chamber body extending between a first end and a second end and elongate along a body axis;
a first inlet bore extending into a first side of the chamber body and to a mix bore extending to a spray orifice, the first inlet bore configured to receive a first component material into the chamber body;
a second inlet bore extending into a second side of the chamber body and to the mix bore, the second inlet bore configured to receive a second component material into the chamber body; and
wherein the mix chamber interfaces with the plural component sprayer within the bore at a keyed interface, the keyed interface formed by a projection extending in to a slot;
