3M 318-4001 Corded Ear Plugs Bell Shape 31 dB 200 Pairs

3M 318-4001 Ear Plugs for Noise Protection

These 3M 318-4001 ear plugs provide a Noise Reduction Rating of 31 dB for workers in loud environments. The bell-shaped foam design uses a push-in insertion method for a secure fit. Each bulk box contains 200 pairs individually wrapped in plastic bags. They suit industrial, construction and workshop settings where consistent hearing protection is required.

Reusable Foam with Vinyl Cord Reduces Loss

The polyurethane foam plugs are reusable and feature a blue vinyl cord that keeps the pair together when not inserted. Corded design prevents individual plugs from falling onto floors or into machinery. Yellow foam colour allows quick visual compliance checks by supervisors. The 31 dB CSA Class AL rating applies when plugs are fitted correctly according to the push-in method.

Universal Size Fits Most Users Without Adjustment

Universal medium sizing eliminates the need to stock multiple size variants across a workforce. Bulk packaging of 200 pairs supports high-turnover sites and reduces reorder frequency. No metal-detectable components are present, so they are not suitable for food-processing lines that require detectable PPE. Users seeking metal-detectable or uncorded options will need a different product.
