Product Details

While most work places provide standard earplugs to help reduce ear damage, an increasing number of employers that care about their workers have begun to step up to a new level and provide their employees with high-class ear plugs like the 3M E-A-R™ UltraFit™. Not only do they offer protection of NRR 25 dB, but the proprietary triple flange design makes insertion into the ear easy and safe, eliminating the need to roll or squish like other earplugs. The soft polymer material makes it easy to wash and reuse. The EAR UltraFit™ plugs come in a variety of selections - corded and uncorded, as well as in small plastic carrying cases or polyethylene bags.

3M recommends UltraFit™ Ear Plugs to be used in applications such as facility maintenance, machine operations, sanding, grinding, blasting, demolitions, and many other operations. For work with electrical arc flash hazards, 3M also makes the same tri-flange earplugs in arc flash safe materials: The 3M E-A-R™ 370-2000 ARC Plug .

Some of the features of the UltraFit plugs are:

  • Safety rating of NRR 25 dB, CSA class AL
  • Triple flange design makes insertion easy and safe
  • Made of soft polymer for easy cleaning and reuse
  • Fits most ear canal sizes
