3M E-A-R UltraFit Earplugs 340-4002

These pre-molded triple-flange earplugs provide a noise reduction rating of 25 dB CSA Class AL. The soft polymer construction is washable and reusable for extended service life. A carrying case keeps the corded plugs clean and accessible between uses. No rolling is required before insertion.

Suited for workers needing reusable hearing

The corded design helps prevent loss in active environments and the case supports hygienic storage. Users who require a higher attenuation rating or a different fit style should consider alternative protection. The one-size triple flange may not seal every ear canal perfectly.

Performance under sustained use

Washable polymer maintains its shape and sealing properties through repeated cleaning cycles. The cord remains attached during long shifts and the case protects the tips from contamination when not worn. NRR 25 dB is verified under standard test conditions.
