This mask supports standard 40mm threaded canisters - sometimes also known as "_nato threaded_" canisters - which the standard dimensions are defined in [sources/dimension/nato_thread_spec.png](./sources/dimension/nato_thread_spec.png).
|
||||
|

This mask can support two separate canisters, which can be advantageous if you need more filtration or less resistance to breathing, especially with smaller canisters. If you want to use a single canister, you can plug the other thread using a 40mm canister plug - one of which can be printed from the provided file (_located at_ [(distorsion/)3D-printed-parametric-40mm-gaz-mask-canister/3Dfiles/nato_thread_plug.stl](https://git.deuxfleurs.fr/distorsion/3D-printed-parametric-40mm-gaz-mask-canister/src/branch/main/3Dfiles)) in the _submodule_ mentioned in the next paragraph.

|
||||
|
||||
To assemble the output one-way valve you can first screw the base ([3Dfiles/one_way_valve/owv_base_cap.stl](./3Dfiles/one_way_valve/)) into the main tube of the adapter, with the smoother surface pointing down, until it is right under the tube that connect to the insuflation mask.

After greasing the surface you can screw the membrane insert ([3Dfiles/one_way_valve/owv_membrane_insert.stl](./3Dfiles/one_way_valve/)_, or equivalently_ [3Dfiles/one_way_valve/owv_separate_membrane.stl](./3Dfiles/one_way_valve/) _and_ [3Dfiles/one_way_valve/owv_separate_membrane_insert.stl](./3Dfiles/one_way_valve/)) until the membrane makes contact with the smooth surface of the base.

If you opted to use an output filter (:warning: _**and have accordingly modified the parameters of the adapter tube**, as shown in the above picture_ :warning:), you can no put the filter aterial (_coton, or some other minimaly ait-restricting material_) at the output of the one-way valve, and thread a cap ([3Dfiles/one_way_valve/owv_base_cap.stl](./3Dfiles/one_way_valve/)) to hold it into place.

There is also an adapter that connects to the gaz mask like an integrated canster and converts it to a 40mm gaz mask. This adapter is requiered as it also hold the one-way valve, which with an integrated canister is held in by the canister.
