The 3M™ Versaflo™ Radiant Heat Cover M-973N is engineered to protect workers operating in extreme heat environments such as foundries, smelters, and high-temperature industrial settings. Designed for seamless compatibility with the 3M™ Versaflo™ M-307 Hard Hat Assembly, this aluminized, aramid-based cover enhances thermal protection for the head, neck, and shoulders without compromising comfort or visibility. Its modular configuration supports integration with over-visors and allows unrestricted visor movement — even with the cover in place — making it ideal for dynamic, high-risk work environments where both respiratory and heat protection are essential.

Key Features

Aluminized Aramid Fabric Construction: Reflects radiant heat while remaining flexible and lightweight — ideal for long shifts near furnaces or molten metal.
Extended Coverage Design: Protects not just the head but also the neck and shoulders, minimizing risk zones exposed to radiant or splash heat.
Flip-Up Compatibility: Allows the main and over-visor to flip up without removing the cover, enabling quick visual checks or communication without compromising protection.
Integrated Breathing Tube Access: Precisely engineered opening keeps the breathing tube connection unobstructed and secure during use.
Tool-Free Assembly with Hook-and-Loop Fasteners: Quick to install and remove on-site, reducing downtime during shift changes or inspections.
Flexible Fit Over Respiratory Headgear: Designed to integrate without interfering with airflow or seal integrity of the 3M™ Versaflo™ M-307 system.
Durability in Harsh Environments: Resistant to abrasion, tearing, and degradation — even when exposed to high heat, heavy use, and repeated inspections.

Intended Use

Workers in metal-processing industries and other high-heat industrial operations require PPE that resists radiant heat, molten splash, and flames while integrating with respiratory protection systems. This head cover adds critical thermal shielding to respiratory setups, minimizing the risk of burns and heat stress.

Foundry workers managing molten metals
Smelting or aluminum production line personnel
Industrial furnace or kiln operators
Glass manufacturing and processing technicians
