3M™ Earplugs 340-4004 Description
The 3MTM E-A-RTM UltraFitTM Corded Earplugs have a “no-roll” design with three flanges that cover your ears quickly, cleanly, and comfortably.
Since the soft polymer earplugs can be washed and used again and again, they don’t need to be changed as often, which saves money and reduces trash.
Some recommended uses are for mechanical and assembly work, chipping, chiselling, cleaning, drilling, furnace work, grinding, heavy equipment work, machining, metal repair, painting, filling or casting, power fixing, riveting, sanding, sawing and welding.
People work in building, general industry, mining, oil and gas, transportation, and other fields often wear these earplugs.
These soft polymer earplugs can block out 25 decibels of noise and can be used with the 3MTM E-A-RfitTM Validation System.
