3M 7000002307 Corded Foam Earplugs 33db 200 Pairs

Product Description

The 3M 7000002307 is a corded, reusable foam earplug designed to deliver a 33 dB Noise Reduction Rating (NRR) in high-noise work environments. The bullet-shaped plug uses a roll-down insertion method: compress the foam, insert into the ear canal, and hold until the plug expands to form a secure acoustic seal. Universal sizing accommodates a wide range of ear canal shapes. The orange cord connects the pair for convenient retrieval and reduces the risk of losing a plug during a shift. Each pack contains 200 pairs, making it practical for bulk deployment in industrial, construction, and manufacturing settings.

These earplugs are suited for sustained noise exposure on job sites, in mechanical rooms, around heavy equipment, or in any environment where ambient noise levels exceed safe thresholds. The reusable foam construction holds its shape through multiple insertions before replacement is warranted. Hearing conservation program administrators, safety managers, and site supervisors typically stock these in quantity to support OSHA hearing protection requirements. The corded design is commonly preferred where dropped earplugs must be kept off floors or equipment surfaces.

Installation Notes

Hearing protection should be fitted by or under the guidance of a qualified safety professional familiar with OSHA 29 CFR 1910.95 hearing conservation requirements. Roll down the foam tip fully before insertion, insert while the plug is compressed, and hold in place until the foam expands to fill the canal. Inspect each plug before use and discard any pair showing tears, hardening, or loss of resilience. Clean hands before handling to maintain plug integrity and hygiene.
