3M 7000002388 Taperfit 2 Probed Test Plugs

Product Description

The 3M 7000002388 TaperFit 2 Probed Test Plugs are modified earplugs equipped with a probe tube designed exclusively for use during earplug fit testing with the 3M E-A-Rfit Validation System. These plugs are not rated for hearing protection and must not be used as standard earplugs in noise-hazardous environments. Sold as a case, they are intended for occupational health and safety professionals, industrial hygienists, and qualified hearing conservation program administrators who conduct individual earplug fit validation testing. The probe tube integration allows the E-A-Rfit system to measure real-ear attenuation and generate a Personal Attenuation Rating for the wearer.

These test plugs are used in workplace hearing conservation programs where OSHA-mandated fit testing protocols are followed. Typical deployment includes manufacturing facilities, construction sites, military installations, and other high-noise industrial environments where documented proof of earplug fit is required. They are used exclusively in controlled fit-testing sessions administered by a trained hearing conservation professional and are not a consumable for general hearing protection inventory.

Key Features

• Integrated probe tube enables real-ear fit testing with the 3M E-A-Rfit Validation System
• TaperFit 2 form factor provides a consistent, repeatable insertion geometry for accurate test results
• Not intended or approved for use as hearing protection
• Sold by the case with a minimum order quantity of 1 case
• Supports documented Personal Attenuation Rating generation for individual workers

Compatibility

Designed for exclusive use with the 3M E-A-Rfit Validation System. These probed test plugs are not interchangeable with standard TaperFit 2 earplugs and are compatible only with the fit-testing hardware and software of that validation platform.

Installation Notes

These plugs are administered by a qualified hearing conservation professional, not self-inserted by untrained end users. Follow the 3M E-A-Rfit Validation System operator procedures for correct probe tube positioning and insertion depth. Do not reuse test plugs beyond the manufacturer-recommended service life for the validation system. No power tools or mechanical fasteners are required; proper hand hygiene and sanitary handling procedures should be observed during each test session.
