3M 7000002387 E-a-r Ultrafit Probed Test Plug

Product Description

The 3M 7000002387 is a probed test earplug designed exclusively for use with the 3M E-A-Rfit Validation System during earplug fit testing. Each plug is modified with an integrated probe tube that allows the system to measure real-ear attenuation during a live fit test. These are not hearing protection devices and must not be worn as such. Safety managers, industrial hygienists, and occupational health professionals use these plugs to validate proper earplug fit for workers in noise-hazardous environments. Fit testing with probed plugs is a core component of a compliant hearing conservation program under OSHA regulations.

The 3M 7000002387 is intended for use in industrial, manufacturing, and occupational health settings where hearing conservation programs require documented earplug fit validation. The probed design works within the 3M E-A-Rfit Validation System, which performs dual-ear simultaneous fit testing. Safety technicians and occupational health staff conduct the testing sessions using these plugs on program participants to generate a Personal Attenuation Rating. This product is sold by the case and is a consumable component of the fit testing workflow.

Key Features

• Integrated probe tube enables real-ear attenuation measurement during fit testing
• Compatible with the 3M E-A-Rfit Validation System for hearing conservation programs
• Not rated or approved for use as hearing protection — test use only
• Supports OSHA-compliant hearing conservation fit testing documentation
• Sold by the case with a minimum order quantity of one case

Compatibility

Designed for exclusive use with the 3M E-A-Rfit Validation System. These probed test plugs are not interchangeable with standard hearing protection earplugs and function only within the E-A-Rfit fit testing workflow.

Installation Notes

These plugs are handled by trained safety or occupational health personnel, not installed by a trade technician in the traditional sense. Before conducting a fit test session, verify the 3M E-A-Rfit Validation System is calibrated and ready per manufacturer guidelines. The probe tube must remain unobstructed during insertion and testing. Do not attempt to use these plugs as hearing protection under any circumstances.
