1. A respirator device, comprising: a body comprising a receiver having an elastomeric sleeve and a rigid outer portion, wherein the receiver defines an aperture in the body, wherein the rigid outer portion is proximate the aperture and, the elastomeric sleeve is adjacent the rigid outer portion such that the rigid outer portion is positioned between the aperture and the elastomeric sleeve; anda rigid nozzle element having an outer surface;wherein inner surfaces of each of the elastomeric sleeve and the rigid outer portion define a channel extending from the aperture, wherein the elastomeric sleeve is configured to deform around the outer surface of the nozzle element when the nozzle element is inserted into the channel, and wherein the outer surface of the nozzle element defines a non-circular shape that prevents rotation between the nozzle element and the rigid outer portion when the nozzle element is inserted into the channel. 2. The respirator device of claim 1, further comprising a filter cartridge, the rigid nozzle element joined to the filter cartridge. 3. The respirator device of claim 1, wherein the elastomeric sleeve comprises an outer surface opposite the inner surface, the inner surface defining the channel, and at least a portion of the outer surface out of contact with a rigid component. 4. The respirator device of claim 1, wherein the elastomeric sleeve is in hoop tension when the nozzle element is inserted into the channel. 5. The respirator device of claim 1, wherein the elastomeric sleeve is in tension in a direction perpendicular to an airflow axis and a radial thickness of the elastomeric sleeve when the nozzle element is inserted into the channel. 6. The respirator device of claim 1, wherein the elastomeric sleeve has a first end portion and a second end portion, and the first end portion is a floating end. 7. The respirator device of claim 1, wherein the elastomeric sleeve has a first end portion and a second end portion, the body includes an interior wall dividing a first chamber and second chamber of an interior space of the body, and the first end portion of the elastomeric sleeve contacts the interior wall. 8. The respirator device of claim 1, wherein the elastomeric sleeve has a first end portion and a second end portion, and the second end portion is sealingly engaged with the body. 9. The respirator device of claim 1, wherein the elastomeric sleeve comprises an outer surface having a perimeter (p), and the perimeter (p) is larger when the nozzle element is inserted in the channel. 10. The respirator device of claim 1, wherein the elastomeric sleeve comprises a first end, a second end, and an outer surface having a perimeter (p), the perimeter (p) varying between the first and second ends. 11. The respirator device of claim 1, wherein the channel defined by the elastomeric sleeve includes a rib around a perimeter of an inner surface. 12. The respirator device of claim 1, wherein the elastomeric sleeve is made from a thermoset material. 13. The respirator device of claim 1, wherein the elastomeric sleeve is made from a silicone. 14. The respirator device of claim 1, wherein the elastomeric sleeve is made from a material selected from the group consisting of injection moldable (high or low pressure) elastomers. 15. The respirator device of claim 1, wherein the elastomeric sleeve has a length (l) in a longitudinal direction between 6 mm and 12 mm. 16. The respirator device of claim 1, wherein the elastomeric sleeve has a wall thickness (t) between 0.5 mm and 2 mm. 17. The respirator device of claim 1, wherein the body is a half-mask body. 18. The respirator device of claim 1, wherein the body is a full-mask body. 19. The respirator device of claim 1, wherein the body is a head-mounted respirator device body. 20. The respirator device of claim 1, wherein the body is a housing of a powered air respirator device. 21. A respirator device, comprising: a body comprising a receiver having an elastomeric sleeve and a rigid outer portion, wherein the elastomeric sleeve is engaged with and extends from the rigid outer portion; anda rigid nozzle element having a leading end, a base end, and an outer surface;wherein inner surfaces of each of the elastomeric sleeve and the rigid outer portion define a channel, wherein the elastomeric sleeve is configured to deform around the outer surface of the nozzle element when the nozzle element is inserted into the channel, and wherein the base end of the nozzle element is closer to the inner surface of the rigid outer portion than the inner surface of the elastomeric sleeve and the leading end of the nozzle element is closer to the inner surface of the elastomeric sleeve than the inner surface of the rigid outer portion.
