3M 7000127182 Uncorded Foam Ear Plugs Nrr 30 Db

Product Description

The 3M 7000127182 is an uncorded foam ear plug sold in a box of 4 pairs, designed for workers in high-noise environments where hearing protection is required. Built around a twist-to-seal insertion method, the plug uses a skull-screw shape that eliminates the need to roll the foam before insertion, reducing contact with the plug body and improving hygiene on the job. The ear plug carries a Noise Reduction Rating (NRR) of 30 dB, placing it in the upper range for single-use disposable hearing protectors. Soft foam construction delivers comfort during extended wear while the distinctive skull-screw geometry helps seat the plug securely in the ear canal.

These ear plugs are suited for industrial, construction, and maintenance environments where sustained high noise levels make hearing protection mandatory. Typical applications include work near HVAC equipment, generators, compressors, power tools, and other loud mechanical systems. The uncorded design is preferred in situations where a connecting cord would interfere with movement or personal protective equipment. The minimum order quantity is 4 boxes, making this packaging suitable for stocking a job site or service vehicle.

Key Features

• NRR 30 dB noise reduction rating for high-noise industrial environments
• Twist-to-seal skull-screw design eliminates the pre-insertion rolling step
• Uncorded format for unrestricted movement and compatibility with other PPE
• Soft foam material provides comfort during extended wear periods
• Sold in box packaging with a minimum order quantity of 4

Compatibility

Designed as a general-use uncorded disposable ear plug for workers requiring ANSI-compliant hearing protection in industrial and trade settings.

Installation Notes

Proper fit is critical for achieving the rated NRR performance. Follow the manufacturer insertion instructions, which typically require twisting the plug and seating it fully in the ear canal rather than rolling. Dispose of plugs per site safety protocols and replace when the foam becomes soiled or loses its ability to expand and seal. Consult applicable OSHA hearing conservation regulations when selecting hearing protection for a specific noise exposure level.
