29 dB NRR foam earplugs for industrial noise

These uncorded foam earplugs carry a Noise Reduction Rating of 29 decibels and meet CSA Class A. Slow-recovery foam expands inside the ear canal to create a low-pressure, custom seal. The plugs are flame-resistant and moisture-resistant for harsh environments. They suit workers in automotive, construction, manufacturing, mining, oil and gas, and transportation settings.

Refill bottle for 3M One Touch Dispenser 391-1000

The bottle is designed to refill the 3M One Touch Dispenser 391-1000, replacing loose packs or bulk bags that can spill. Switching to the bottle makes sense when a fixed dispensing point improves hygiene and reduces waste on the shop floor. The 391-1001 refill keeps the dispenser stocked without handling individual pairs.

Workers who need high-attenuation disposable plugs

This product fits users who require a 29 dB NRR disposable plug compatible with the 391-1000 dispenser system. It is not intended for buyers who need corded or reusable earplugs, nor for those who require a different attenuation rating or a dispenser model other than the 391-1000.
