3M 7000127175 Disposable Foam Earplugs Large 33 Db Nrr

Product Description

The 3M 7000127175 is a large-size disposable foam earplug designed for workers with larger ear canals who need reliable hearing protection in high-noise environments. Each earplug is made from soft, low-pressure foam that rolls down easily for insertion, then expands within the ear canal to create a consistent acoustic seal. With a Noise Reduction Rating (NRR) of 33 dB and a CSA Class AL rating, this earplug meets the demands of industrial job sites where sustained noise exposure is a daily concern. Each pair is individually packed in a poly bag to keep earplugs clean until the moment of use.

This earplug is suited for use in industrial, construction, manufacturing, and mechanical service environments where personnel are exposed to elevated noise levels. The large size designation makes it a practical option for hearing conservation programs that require fit-tested validation. It is test compatible with the 3M E-A-Rfit Validation System, supporting documented fit-testing protocols commonly required in formal hearing conservation programs under OSHA 29 CFR 1910.95. The case format supports site-level distribution and inventory management for safety coordinators and service contractors.

Key Features

• 33 dB NRR and CSA Class AL rating for high-noise industrial environments
• Large size designed for workers with larger ear canals
• Soft, low-pressure foam rolls down easily for consistent insertion and fit
• Foam expands within the ear canal to form an acoustic seal after insertion
• Individual poly bag packaging keeps each pair clean before use
• Test compatible with the 3M E-A-Rfit Validation System for fit-testing programs

Compatibility

Compatible with the 3M E-A-Rfit Validation System for hearing protection fit testing. Designed as a large-size disposable earplug for use in standard hearing conservation programs requiring uncorded foam-type hearing protectors.

Installation Notes

Earplugs should be fitted by rolling the foam into a tight cylinder before insertion into the ear canal, then held in place until the foam fully expands. Safety coordinators and industrial hygienists should follow OSHA 29 CFR 1910.95 guidelines when deploying hearing protection as part of a formal conservation program. Earplugs are single-use and disposable — do not reuse after removal. Per 3M guidance, the NRR should be reduced by 50 percent when estimating real-world attenuation during typical use conditions.
