3M 7100155188 Disposable Foam Earplugs Nrr 32 Db 7 Pair

Product Description

The 3M 7100155188 is a disposable, uncorded foam earplug designed for hearing protection on active jobsites. Each earplug is made from ultra-soft foam that compresses for insertion and slowly expands to conform to the ear canal, creating a secure acoustic seal. With a Noise Reduction Rating (NRR) of 32 dB, these earplugs are suited for high-noise environments including construction, mechanical rooms, and industrial settings. The orange color keeps them visible on busy worksites. Each pack contains 7 pairs. Licensed tradespeople and safety supervisors commonly stock these for crew distribution on noise-intensive jobs.

These earplugs are intended for general jobsite use where disposable hearing protection is required. They are a practical choice for HVAC techs, electricians, plumbers, and other tradespeople working near loud equipment such as compressors, generators, power tools, and HVAC systems. The one-size design fits a wide range of ear canal sizes, reducing the need to manage multiple sizes on a jobsite. They can also be worn in combination with earmuffs for dual hearing protection in extreme-noise environments.

Key Features

• NRR 32 dB noise reduction rating for use in high-noise work environments
• Slow-expansion foam conforms to a wide range of ear canal sizes for a reliable fit
• Soft, smooth surface material supports extended wear comfort
• Uncorded, disposable design for quick deployment and easy replacement
• High-visibility orange color for easy identification on the jobsite
• Compatible with earmuffs for dual-protection use in extreme-noise settings

Compatibility

Designed as a general-use disposable earplug suitable for trade and industrial jobsite hearing protection programs where disposable, uncorded foam earplugs are specified.

Installation Notes

Roll the earplug into a tight cylinder before insertion, then reach over the head to straighten the ear canal and insert the compressed plug. Hold it in place for several seconds while it expands to form a seal. These are single-use disposables and should not be reused after a full workday. Proper fit is required to achieve the rated NRR; 3M recommends fit testing, and notes that actual attenuation may be lower than the labeled NRR depending on fit and user technique.
