3M 7000127215 Corded Foam Earplugs 31 Db Nrr Csa Class Al

Product Description

The 3M 7000127215 is a corded foam earplug designed for occupational hearing conservation in loud work environments. Built with 3M E-A-Rform Foam, the earplug material conforms to the shape of the ear canal, creating a noise-reducing seal that delivers a Noise Reduction Rating (NRR) of 31 dB. A flexible, pistol-grip handle and stem give the installer or wearer fingertip control for clean, consistent insertion without pressing foam directly with bare hands. This design helps reduce dirt transfer and supports better hygiene on the job site. Suitable for all-day wear, these earplugs are appropriate for industrial, construction, and facility maintenance settings where sustained noise exposure is a concern.

These earplugs are intended for use in high-noise occupational environments including HVAC mechanical rooms, construction sites, manufacturing floors, and other trade workplaces where continuous or impact noise exceeds safe exposure thresholds. The corded design keeps earplugs paired and accessible, reducing loss during intermittent use. The tapered-cone shape and smooth foam surface promote consistent fitment across a range of ear canal sizes. Supplied in case quantity with a minimum order of one case, making them suitable for stocking in job site safety kits or fleet service vehicles.

Key Features

• 31 dB Noise Reduction Rating (NRR) for significant attenuation in high-noise environments
• CSA Class AL certified for use in Canada under applicable hearing protection standards
• 3M E-A-Rform Foam conforms to individual ear canal shape for a consistent seal
• Pistol-grip handle and stem allow insertion without direct contact with the foam tip, reducing contamination
• Tapered-cone profile and smooth surface support comfort during extended wear
• Corded design keeps both earplugs connected and reduces the chance of loss between uses

Compatibility

Designed as a general-purpose corded foam earplug for occupational hearing protection programs in trade and industrial settings. No specific equipment compatibility required.

Installation Notes

Earplugs should be fitted by the end user following the instructions provided with the product packaging. For accurate hearing protection, proper insertion technique is critical — improper fit significantly reduces effective attenuation. Employers should refer to OSHA 29 CFR 1910.95 or applicable regional regulations when establishing a hearing conservation program. 3M recommends reducing the labeled NRR by 50 percent when estimating real-world noise reduction during typical use.
