Need a fresh exhalation valve cover for your 3M Ultimate FX full-face respirator? This 5-pack of FF-400-09 covers fits models FF-401, FF-402, and FF-403. They protect the valve from debris and keep your respirator performing like new. Swapping them out is cheaper than replacing the whole mask, and it's super easy—just pop the old one off and snap the new one on. Keep a few spares in your gear bag for when they get dirty or worn. Essential for painters, woodworkers, or anyone using these respirators in dusty or chemical environments.
