Earmuff Hygiene Kit – Suits HRE663, HRE664 & HRE646

Keep your hearing protection performing at its best with this replacement earmuff hygiene kit, designed to suit earmuff models HRE663, HRE664 and HRE646. In high-use Australian worksites such as construction, mining and manufacturing, earmuffs are exposed to sweat, dust, oils and daily wear. Replacing worn cushions and inserts helps maintain a consistent seal around the ear, supporting dependable attenuation, improved comfort and better day-long compliance on site.

This kit is a practical, cost-efficient maintenance solution for safety managers and store teams looking to extend the service life of existing earmuffs and reduce unnecessary full-unit replacement. Fresh cushions improve fit and reduce pressure points, helping workers keep protection on for the full shift—especially in hot, humid or high-dust environments. Regular hygiene replacement also supports cleaner shared PPE, which is critical for crew rotations and visitor use.

Ideal for site-issued PPE programs, shutdown toolboxes and maintenance cribs, this hygiene kit is supplied as a single pack for straightforward inventory control. Use it as part of scheduled PPE inspections to minimise downtime, lift comfort and maintain consistent hearing protection performance across your workforce.

Note: Technical specifications and certification details should be confirmed with the manufacturer for your internal compliance documentation.
