3M Ear Plug Refill 33dB PK400

This refill pack supplies 400 yellow foam ear plugs for compatible 3M dispensers. Each bell-shaped plug is sized large and rated at 33dB attenuation. The product is new and intended for workplaces that need a high-volume supply of hearing protection. It suits safety managers who restock dispensers on a regular basis.

Foam material and bell shape

The HAWA foam compresses for insertion and expands to fill the ear canal, while the bell profile helps seat the plug securely. Yellow colour makes the plugs easy to spot during compliance checks. The pack contains only the refill units; no dispenser hardware is included. Buyers who need a dispenser or a different plug size must source those separately.

Questions about this item

How often will the 33dB foam earplugs need replacing?

Each pair is single-use; the pack contains 400 pairs so you replace them as soon as they become soiled or lose shape.

What limits comfort during a full shift wearing these bell-shaped plugs?

The low-pressure foam expands to fit the ear canal, and the bell shape reduces pressure points during extended wear.
