3m Earplugs 340-4004 E-A-R UltraFit

Invest in advanced, long-lasting hearing protection with the 3M™ E-A-R™ UltraFit™ Earplugs, product number 340-4004. Engineered specifically for rigorous commercial and industrial environments, this premium reusable earplug solution from 3M delivers all-day comfort and reliable noise reduction. This offering provides exceptional value, including a case of 400 pairs of corded earplugs, each individually packaged in a hygienic polybag for convenient distribution and storage across your site.

The core of this exceptional hearing protector is its innovative triple-flange design. This feature allows these 3m earplugs to contour and adapt seamlessly to the unique shapes and sizes of most ear canals, ensuring a secure, consistent, noise-blocking seal every single time. Crafted from a pliable, soft elastomeric polymer, the UltraFit™ is built for extended wear, minimizing irritation and maximizing user compliance. Unlike standard disposable alternatives, this resilient polymer is fully washable and reusable, significantly reducing long-term replacement costs and minimizing environmental waste, making the 3M 4004 an exceedingly practical and economical choice.

User safety and ease of use are paramount design features. The earplugs incorporate a semi-rigid stem that facilitates easy, contamination-free insertion into the ear canal without requiring users to touch the ear tip. With a reliable Noise Reduction Rating (NRR) of 25 dB, these yellow, corded protectors are suitable for a wide range of demanding applications, including Grinding, Welding, Sanding, and Machine Operations across essential industries such as Automotive, Construction, and General Manufacturing. Furthermore, the 340-4004 is compatible with the 3M™ E-A-Rfit™ Validation System, allowing safety managers to accurately test and confirm that each worker is receiving their expected level of protection. Choose the 3M 4004 for a proven combination of top-tier performance, enhanced user compliance, and cost-effectiveness.

7. *U.S. EPA specifies the NRR as the measure of hearing protector noise reduction. However, 3M makes no warranties as to the suitability of the NRR for this purpose. 3M strongly recommends personal fit testing of hearing protectors. Research suggests that users may receive less noise reduction than indicated by the attenuation label value(s) on the packaging due to variation in fit, fitting skill, and motivation of the user. Refer to applicable regulations or guidance on how to adjust attenuation label values. It is recommended that the NRR be reduced by 50% to better estimate typical protection.
8. Vinyl or cloth material options for cords
