Tappo auricolare riutilizzabile 3M 1100C4, arancione, con cordino, confezione da 4

3M 1100C4 reusable ear plugs in orange are corded ear protection made from slow-recovery polyurethane foam with a tapered shape. Supplied as a pack of four pairs, they are designed for repeated use and convenient handling thanks to the attached cord. These lightweight plugs offer high-level attenuation and are intended for general noise reduction in workshops, DIY, events and similar environments.

Advantages

The soft, slow-recovery polyurethane foam conforms to the ear canal for a comfortable fit and becomes softer with body heat. The tapered design helps achieve a reliable seal for many ear shapes. The corded configuration keeps pairs together for easier storage and handling, and the plugs are lightweight while providing effective noise reduction up to 37 dB.

Suitable for

When it may not be suitable

These corded foam plugs are intended for repeated use but are not permanent hearing protection; they are disposable after the foam shows wear, contamination, or reduced performance. They may not be appropriate where very high hygiene standards require single-use, sterile ear protection or where custom-moulded earplugs are needed for an optimal fit.

Key specifications

How to use

Compress and roll the foam plug between fingertips to form a narrow cylinder, gently pull the top of the ear upward and backward to straighten the ear canal, then insert the compressed plug and hold until it expands to form a seal. Use the cord to keep plugs together when not in use. Inspect before each use and replace if dirty, torn or no longer expanding properly.

What to consider before purchase

Recommendations

Use these corded foam ear plugs for intermittent or repeated protection in noisy tasks such as sanding, drilling, sawing and mowing. Replace plugs when they become dirty, misshapen, or fail to expand fully; store them in a clean container when not in use to prolong usable life.
