The MIRA Safety Gas Mask Replacement Parts Kit contains every critical wear component needed to restore a MIRA Safety respirator to full working condition. Available in two configurations — the Essentials Kit and the Deluxe Kit — this kit is compatible with the CM-6M (all variants), CM-7M, CM-8M, and TAPR gas masks. Wear parts require replacement at minimum every five years for masks held in storage, and more frequently for masks in active tactical use.
This kit is designed specifically for the MIRA Safety CM-6M (all variants), CM-7M, CM-8M, and TAPR. Inner mask valves are included in all kits, but are not required for the CM-7M, CM-8M, or TAPR — only the CM-6M uses the oro-nasal cup inner valves. These parts are not compatible with any smaller gas masks designed for children. For the Deluxe Kit, the head harness design differs between the CM-6M and the CM-7M, so select the correct variant for your mask model at checkout.
Every component in this kit performs a specific protective function. Replacing them on schedule keeps your mask airtight and performing as designed.
| Component | Qty | Function |
|---|---|---|
| Inner Mask Valves | 4 | Mount on the oro-nasal cup; prevent backflow of filtered air through the inhalation ports and help redirect exhaled CO2 away from the lens to reduce fogging |
| Exhalation Valve | 1 | Expands on exhalation, then snaps shut to maintain a sealed environment; the mask cannot function properly without a serviceable exhalation valve |
| Exhalation Valve Cover | 1 | Protects the exhalation valve from physical damage; replace if any damage or deformation is visible |
| 40 mm Plug | 1 | Blocks one of the two filter ports to allow single-filter use, reducing overall weight and improving rifle-shoulder clearance |
The Deluxe Kit includes all four components above plus one replacement head harness. The head harness should be replaced every 10 years, or sooner if the elastic shows stretching or visible damage. Because the harness geometry differs between the CM-6M and the CM-7M, the Deluxe Kit is sold in model-specific variants — confirm your mask model before ordering.
Elastomeric and rubber components degrade over time even without use. For masks in storage, all wear parts should be replaced at minimum every five years. Masks in active tactical use require more frequent inspection and earlier replacement. The head harness has a longer service life and should be replaced at the 10-year mark or whenever elastic integrity is compromised.
Installation is straightforward, but having the parts installed by a professional respirator service center is the recommended approach. Professional service centers use a negative pressure fit tester to confirm no leaks remain after new components are seated. If you install the parts yourself, perform a negative pressure test before returning the mask to service to verify the seal is intact. MIRA Safety and its affiliates are not responsible for incorrect assembly, improper maintenance, or mask modifications.
This kit is compatible with the MIRA Safety CM-6M (all variants), CM-7M, CM-8M, and TAPR. It is not compatible with any MIRA Safety masks sized for children. If you own a CM-7M, CM-8M, or TAPR, note that the included inner mask valves are not required for those models.
It depends on how old your head harness is. If the harness is under 10 years old and the elastic shows no damage, the Essentials Kit covers every other critical wear part. If the harness is near or past the 10-year mark, or if the elastic is stretched or degraded, choose the Deluxe Kit. Select the Deluxe Kit variant that matches your specific mask model — CM-6M and CM-7M use different harness designs.
Yes, but a professional respirator service center is the recommended approach. Service centers use a negative pressure fit tester to verify the seal after installation. If you install the parts yourself, perform a negative pressure test before putting the mask back into service. Improper assembly can compromise the mask's protective seal.
At minimum every five years for a mask in storage. Masks used in active tactical or operational settings need inspection and replacement on a more frequent schedule. The head harness has a longer service life and should be replaced every 10 years or sooner if elastic degradation is visible.
MIRA Safety gas masks have two filter ports. The 40 mm plug blocks one port so you can run a single filter, reducing weight and improving mobility — particularly useful when shouldering a rifle. The plug does not affect the mask's protective performance when a single properly sealed filter is installed in the open port.
Yes. If you are unsure which kit variant matches your mask or whether you need the Essentials or Deluxe configuration, contact us and we will confirm the correct selection before you order.
