The AG 9 was a copy of the Italian Rifugio T.U.O./M.N. made by Sacic for Belgian passive civilian use. It differed in the thread of the inlet, the colour of the furniture and the kit.
Mask overview[]

Side view of the AG 9
The faceblank is made of a thin sheet of beige stamped rubber, seamed at the bottom, to which the following
are attached:
- Inlet-outlet assembly
- Eyepieces
- Head-harness
The inlet-outlet assembly is made of aluminium and is connected to the mask with wire and rubberized tape. It has two threads, one for the cap that keeps the exhale valve in place and the other for the filter. The latter has a metal tab that keeps the inlet valve in place. The thread on the inlet is 25 mm
The lenses, made of cellulose acetate, are inserted each in a circular pocket and secured with aluminium frames.
The head harness has two straps, one that connects the end of the rubber appendages on the side of the faceblank and one that connects to the front and has a loop at the end to link the other strap so that a pseudo-three-straps-harness is made.
