About this product

Maintain Your Respirator for Long-Term Reliability

The MIRA Safety® Gas Mask Valve Replacement Kit contains the essential replacement components needed to help maintain compatible MIRA Safety® full-face respirators. Rubber valves and sealing components naturally age over time, making routine maintenance an important part of keeping your equipment in proper working condition.

Whether you're replacing worn components or refreshing a long-term stored respirator, this kit provides the key valve components used in compatible MIRA Safety® gas masks.

What's Included

• (4) Inner Mask Valves*
• (1) Exhalation Valve
• (1) Exhalation Valve Cover
• (1) 40 mm Port Plug

40 mm Port Plug

Most MIRA Safety® gas masks feature dual 40 mm NATO filter ports. The included port plug allows one port to be sealed, enabling operation with a single filter for a lighter, more streamlined configuration.

Compatibility

Compatible with:

• CM-6M® 
• CM-7M®
• CM-8M®

Please note that the inner mask valves included in this kit are only used on the CM-6M®.

Not compatible with children's respirators.

Installation & Safety

Although installation is relatively straightforward, MIRA Safety® recommends having replacement components installed by a qualified respirator service center. Professional service centers can verify the respirator maintains a proper seal using specialized fit-testing equipment.

If installing the components yourself, always perform a negative-pressure user seal check before placing the respirator into service.

MIRA Safety® and its affiliates are not responsible for improper installation, incorrect assembly, unauthorized modifications, or inadequate maintenance.
