RPB Quiet-Link Helmet Earmuffs – 25 dBA Attenuation, For T-Link & Z-Link, Replaces Side Padding System, Also Compatible with Z4 Welding Respirator

Part Number: 18-533
Weight: 0.81 lbs
Compatibility Notice: Not compatible with the Comms-Link™ Communication System.

The 18-533 RPB® Quiet-Link™ Helmet Earmuffs provide high-performance hearing protection with 25 dBA attenuation, designed specifically for operators using T-Link®, Z-Link®, and Z4® welding respirators. These earmuffs completely replace the standard Side Padding System to deliver superior noise reduction in high-decibel industrial environments such as blasting, grinding, fabrication, heavy manufacturing, and welding operations.

Engineered for comfort, durability, and seamless helmet integration, Quiet-Link™ earmuffs maintain a secure fit while allowing the respirator to move naturally with the user’s head. The low-profile design ensures compatibility with hood movement and maintains proper respirator balance without adding unnecessary bulk or discomfort.
