The adapter nut M22 × 1 (BTZ00140) secures the emergency button gas-tight in the frame face of the gas-tight hinged door. It is screwed onto the button thread from the front of the door frame and presses the button against the frame surface.

The O-ring NOR01106, which permanently seals the lead-through, is positioned between the adapter nut and the frame. The adapter nut is made of stainless steel and thus matches the surface of the door frame.

The adapter nut is supplied individually. The emergency button and O-ring are not included in the scope of delivery. One adapter nut is required per emergency button.
