RPB Nova 3 Breathing Tube

Part Number: NV3-2021B
Weight: 0.80 lbs

The RPB® Nova 3® Breathing Tube is an OEM replacement air supply hose engineered to deliver clean, consistent breathing air to operators using the Nova 3® respirator. Built for durability and flexibility in harsh blasting environments, this breathing tube maintains proper airflow while ensuring unrestricted movement during high-demand abrasive blasting applications.

Designed to connect securely between the helmet and the air supply source, the tube resists crushing, kinking, and abrasion—preserving airflow and operator safety. Regular replacement of breathing tubes is recommended to maintain optimal respiratory protection and prevent airflow restrictions caused by wear, media buildup, or workspace contamination.
