3M E-A-R UltraFit Corded Ear Plugs
These reusable ear plugs suit workers who need hearing protection they can keep in place all shift. The flanged elastomeric polymer design allows quick push-in insertion without rolling foam. A white cloth cord prevents loss when the plugs are removed temporarily. They are sold new in a bulk box of one hundred pairs.
Flanged Polymer Build and Corded Convenience
The yellow elastomeric polymer flanges create a seal that can be washed and reused, reducing waste compared with single-use foam. Universal medium sizing fits most ear canals without the need for multiple sizes. The integrated white cloth cord stays attached to the band so the plugs hang around the neck when not inserted. Bulk packaging in individual plastic bags keeps each pair clean until use.
25 dB Noise Reduction Rating
The plugs carry a noise reduction rating of twenty-five decibels and meet CSA Class AL standards for occupational hearing protection. This attenuation level determines whether the product matches the noise environment of the job site. Buyers who require higher attenuation for very loud industrial settings will need a different solution. No metal-detectable version is offered in this pack.

Questions about this item
What noise reduction does the 25 dB CSA Class AL rating actually deliver?
The plugs carry a Noise Reduction Rating of 25 dB and meet CSA Class AL, meaning they are tested to reduce typical industrial noise by roughly 25 decibels when fitted correctly.
What ear-canal size does the universal medium flange fit?
The flanged medium design suits most adult ear canals; the elastomeric polymer cones taper to seal a wide range of diameters without needing multiple sizes.
How do I insert the push-in plugs so they seal properly?
Roll each flange slightly, pull the outer ear up and back, push the plug in until the flanges sit flush, then hold a few seconds — skipping the ear-pull step is the common mistake that leaves gaps.
