The PTFE seal (HBZ02343) seals the inspection cover of the safety interlock on the door leaf of the gas-tight hinged door from HT Group. It is positioned between the inspection cover and the door leaf shell and is bolted in place together with the cover. This ensures that the service opening in the door leaf remains permanently sealed gas-tight.

The seal is made of 2 mm thick, biaxially stretched PTFE and is not self-adhesive. Its outer dimensions of 175 × 225 mm and inner cutout of 135 × 185 mm correspond to the inspection cover; the eight Ø 7 mm holes match its bolt pattern.

The cover is bolted using M6 screws (NOR01541 or NOR00696) and sealing washers HBZ04286, ensuring the screw connections are also gas-tight. We recommend checking the seal for damage each time the inspection cover is removed and replacing it if necessary.
