3M 7000052879 E-a-r Express Podplugs Probed Test Plugs

Product Description

The 3M 7000052879 is a set of probed test earplugs designed for use with the 3M E-A-Rfit Validation System during earplug fit testing procedures. Each plug is modified with an integrated probe tube that allows the fit-testing system to measure attenuation performance in real time. These are not hearing protection devices and must not be used as such. Hearing conservation program administrators, industrial hygienists, and occupational health professionals use these plugs as part of a structured, quantitative fit-testing protocol to verify proper earplug fit for workers in noise-hazardous environments.

These probed test plugs are intended exclusively for fit-testing sessions conducted with the 3M E-A-Rfit Dual-Ear Validation System. They are used in industrial, manufacturing, and occupational health settings where regulatory or program requirements call for documented earplug fit verification. A trained technician or hearing conservation professional typically administers the test. The plugs are sold as a case quantity and are compatible with the E-A-R EXPRESS PodPlugs fit-testing workflow.

Key Features

• Integrated probe tube enables real-time attenuation measurement during fit testing
• Designed exclusively for use with the 3M E-A-Rfit Validation System
• Based on the E-A-R EXPRESS PodPlug form factor for consistent, repeatable test results
• Not rated for hearing protection — for fit-testing use only
• Sold by the case with a minimum order quantity of 1 case

Compatibility

Designed for use with the 3M E-A-Rfit Validation System as part of a hearing conservation fit-testing program. These plugs are not interchangeable with standard hearing protection earplugs.

Installation Notes

These test plugs are administered by a qualified hearing conservation professional or trained technician following the 3M E-A-Rfit system protocol. Do not insert or remove the probe tube from the plug body, as this will compromise test accuracy. Plugs are single-use items and should be discarded after each fit-testing session. Follow all applicable OSHA hearing conservation program requirements when conducting fit testing.
