Moldex Rockets® 6400 / 6405 Reusable Silicone Ear Plugs – Corded & Uncorded Options

Moldex Rockets® reusable ear plugs are designed for workers who need reliable hearing protection that lasts beyond a single shift. Made from soft, durable silicone, these ear plugs provide a secure yet comfortable seal that can be washed and reused multiple times, making them ideal for construction, industrial, manufacturing, and maintenance environments where hearing protection is worn daily.

The Rockets® design features a multi-curved, triple-flange shape that fits a wide range of ear canals without rolling, while the rigid center stem allows for easy insertion and removal—even when wearing gloves. Both corded and uncorded options are available to match different worksite needs, from active jobsite use to controlled indoor environments.

These ear plugs meet ANSI S3.19 testing standards and provide a Noise Reduction Rating (NRR) of 27 dB, helping reduce harmful noise exposure while still allowing situational awareness on the job.

Available Styles

• Uncorded (Model 6400) – Ideal for stationary or controlled work environments
• Corded (Model 6405) – Helps prevent loss during intermittent use or active movement
