Replacement Head Harness

The included replacement head harness is designed specifically for the CM-7M® Military Gas Mask. Over time, elastic components can stretch, lose tension, or become damaged through normal use and storage. Replacing the harness helps maintain a secure, comfortable fit.

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 only with:

• CM-7M®

Not compatible with the CM-6M®, CM-8M®, or 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.
