3M 7000042881 Foam Earplug Refill 33db Nrr 2000 Count

Product Description

The 3M 7000042881 is a refill container of uncorded foam earplugs designed for use with the 3M One Touch dispenser system. Each container holds 2000 regular-size earplugs made from soft, slow-recovery foam that seals the ear canal to deliver a Noise Reduction Rating (NRR) of 33 dB. An orange fitting ring on each earplug provides a visual guideline for proper insertion and allows supervisors to perform quick compliance checks on the floor. Earplugs roll down easily for insertion and expand within the ear canal for a secure, comfortable fit. This refill is suited for high-volume hearing protection programs in industrial, construction, and manufacturing environments.

This refill is intended for facilities running the 3M One Touch dispenser system. One gentle turn of the dispenser delivers a single pair of earplugs, keeping the supply sanitary and reducing waste. The regular size fits most adult ear canals, making it a practical choice for general-workforce hearing protection programs. The 7000042881 is also test-compatible with the 3M E-A-Rfit Validation System, which allows employers to conduct individual fit testing to verify adequate protection levels for each worker.

Installation Notes

Load the refill container into a compatible 3M One Touch dispenser according to the dispenser manufacturer instructions. Safety coordinators and industrial hygienists should train workers on proper roll-down insertion technique to achieve the rated NRR. Per 3M guidance, reduce the labeled NRR by 50 percent when estimating real-world noise attenuation during typical use. Inspect ear canals for contraindications before issuing earplugs, and consult applicable OSHA 29 CFR 1910.95 hearing conservation requirements for program compliance.
