The O-ring 24 × 2.5 mm (NOR01106) seals the emergency button feed-through in the frame face of the gas-tight swing door. It is positioned between the adapter nut BTZ00140 and the door frame and is compressed by pressing in the adapter nut.

Without the O-ring, the gas-tight seal at the button feed-through is not maintained. We therefore recommend replacing the O-ring each time the button is disassembled.

One O-ring is required per emergency button. The O-ring is made of NBR 70 and has an inner diameter of 24.0 mm with a cord thickness of 2.5 mm.

Intended use

Replacement and service component for gas-tight swing doors (GDDT) in laboratory, cleanroom, and security areas.
