MSA 78703 Exhalation Valve Overview

The MSA 78703 is a replacement exhalation valve designed for respiratory protection equipment. It fits Comfo Classic half mask respirators and Ultra Twin full face respirators.

Compatibility Check Before Ordering

Verify that your respirator model matches the listed compatible part numbers: 471286, 471298, 471310, 480259, 480263, 480267, 808071, 808072, 808073, 808074, 808075 or 808076. This valve is specific to MSA Comfo and Ultra-Twin series units. It will not fit other brands or respirator series not listed above.

Valve Function and Maintenance Impact

The exhalation valve directs expelled air out of the respirator while preventing outside contaminants from entering during inhalation. Replacing a worn or damaged valve restores the intended breathing resistance and seal integrity. No additional accessories or software are included; the component is a single mechanical part for direct user replacement.

How does the 78703 valve affect breathing resistance when fitted to a Comfo Classic half mask?
