Moldex 6615 Sparkplugs Corded Foam Earplugs 33 Db Nrr

Product Description

The MOLDEX 6615 SparkPlugs are disposable, corded foam earplugs designed for consistent hearing protection in high-noise industrial and trade environments. Built from extra-soft, low-pressure foam with a tapered profile, these earplugs insert easily into the ear canal and create a gentle, snug acoustic seal. The 6615 carries a Noise Reduction Rating of 33 dB, the highest independently tested NRR available, making it appropriate for the majority of occupational noise exposures. The attached cord keeps pairs together during intermittent-use tasks. Weighing 1.15 pounds per box, the unit ships as a box with a minimum quantity of 20 pairs per order.

These earplugs are suited for use in construction, HVAC mechanical rooms, electrical utility work, manufacturing floors, and any job site where sustained noise levels exceed safe exposure thresholds. The tapered foam shape accommodates a wide range of ear canal sizes, including very small canals, reducing the need for multiple SKUs across a mixed crew. The corded design is practical for technicians who remove and reinsert protection frequently throughout a shift.

Key Features

• NRR 33 dB — highest independently tested noise reduction rating, tested to ANSI S3.19-1974 by Michael Associates, Inc.
• Extra-soft, low-pressure foam reduces in-ear fatigue during extended wear
• Tapered shape allows easy insertion and clean removal without tools or pre-rolling required
• Corded design keeps pairs connected for repeated on-off use common in trade work
• Fits very small ear canals — one size accommodates most workers
• 100 percent PVC-free foam construction
• Non-irritating smooth surface compatible with other PPE such as safety glasses and hard hats

Compatibility

Designed as a single-use disposable earplug suitable for general occupational hearing protection programs across construction, industrial, and mechanical trades where OSHA-compliant hearing conservation is required.

Installation Notes

Earplugs should be fitted by a qualified safety officer or trained supervisor as part of a documented hearing conservation program under OSHA 29 CFR 1910.95 or applicable state equivalent. Inspect each plug before use and discard any that show tears, hardening, or loss of resilience. Do not reuse disposable earplugs beyond a single work shift. Workers should be trained on proper insertion technique to achieve the rated NRR attenuation.
