Viewport Safety Covers

Torr polycarbonate viewport safety covers are designed to protect the users from flying glass in the event of a Conflat® viewport failure whilst under vacuum.

We recommend the fitting of safety covers on all viewports on your vacuum system. 
If access to a viewport is needed, the cover can be easily removed and then replaced afterwards.
No installation or removal tools are required.

Manufactured by thermo-forming 2mm thickness Makrolon® Clear 099 sheet; a clear polished UV-stabilised solid polycarbonate material with high impact resistance.
Makrolon® Clear 099 has a fire rating to UL94 V0 in the USA and to EN 13501 (B s1 d0) in Europe.

Please note – These safety covers are not suitable for bakeout and must be removed before baking the system. During bakeout, the vacuum viewport should be covered by a layer of aluminium foil to minimise temperature differentials.
