3M 340-4007 Earplugs Tracer Nrr-21 W/Cord, Box Of 100 Pairs

The 3M E-A-R UltraFit Metal Detectable Earplugs are designed to provide effective hearing protection in demanding industrial environments. These reusable earplugs address the critical need for noise reduction while also offering metal detectability to prevent foreign object contamination in sensitive production areas.

• Increased safety due to metal-detectable features in both the ear tip (elastomeric polymer) and the cord, critical for quality control in process industries.
• Enhanced durability and cleanliness because the soft polymer material is washable and reusable, offering a cost-effective solution for hearing protection.
• Improved ease of use with a patented tri-flange design and a longer stem that assists in easy insertion, helping ensure proper fit and consistent attenuation.

These earplugs are specifically designed for workers and quality control staff in the food and beverage and pharmaceutical industries where foreign object detection is mandatory and consistent, reusable hearing protection is needed.

These earplugs have a Noise Reduction Rating (NRR) of 25 dB and are compatible with the 3M E-A-Rfit Validation System for personal fit testing.
