3M 92050H4-C Disposable Foam Earplugs Nrr 32 Db

Product Description

The 3M 92050H4-C is a 4-pair pack of disposable foam earplugs rated at NRR 32 dB, designed for consistent hearing protection in high-noise work environments. Each earplug uses self-adjusting foam that conforms to the ear canal, delivering low insertion pressure while maintaining strong sound attenuation. The foam material is dermatologically tested and non-irritating to the skin, making it suitable for extended wear during full shifts. Licensed HVAC technicians, electricians, plumbers, and other trade professionals working near loud equipment will find these a practical single-use option that requires no special fitting technique.

These earplugs are intended for use in industrial, commercial, and trade environments where ambient noise levels exceed safe exposure thresholds. Typical applications include mechanical rooms, generator areas, compressor bays, job sites with power tools, and any setting where OSHA noise exposure limits are a compliance concern. Each pack contains 4 pairs, and the unit of measure is sold individually (EA) with a package quantity of 20 units available.

Installation Notes

Disposable earplugs require no installation tooling. Roll the foam cylinder tightly between clean fingers, reach over the head to straighten the ear canal, insert, and hold in place until the foam fully expands. Earplugs should be discarded after each use and replaced with a fresh pair. Consult applicable OSHA 29 CFR 1910.95 noise exposure requirements when selecting hearing protection for a specific work environment.
