3M 14231 Folding Ear Muff Hearing Protector Nrr 23 Db

Product Description

The 3M 14231 is a folding ear muff hearing protector designed for job-site noise reduction in trade and industrial environments. It carries a Noise Reduction Rating (NRR) of 23 dB when used as directed, providing reliable attenuation in moderate to high-noise settings such as mechanical rooms, rooftop HVAC service, and construction sites. The unit weighs 0.5 pounds, making it light enough for extended wear during a full shift. An adjustable headband and pivoting ear cups allow the muff to conform to a wide range of head sizes without tool modification.

The 14231 is suited for residential and commercial trade work where consistent hearing protection is required. HVAC technicians, plumbers, electricians, and pool equipment service pros working near loud compressors, generators, power tools, or pump rooms will find this muff practical for day-to-day use. Its one-size-fits-most design makes it a straightforward stock item for service vans and job trailers. The folding frame reduces bulk during transport and storage.

Installation Notes

No tools or installation are required. Position the ear cups fully over each ear and adjust the headband until the cups form a firm seal against the head.

Follow OSHA and employer hearing conservation program guidelines when selecting and using hearing protection.
