The top peep hole USK series is a screw type which is directly attached onto the lid, so it is space saving. The glass is welded with the metal ring so adhesive is not required. This USK series is applicable for the standard “2nd class pressure vessels”.
The peep hole is attached onto the lid to check the materials inside the tank. It can be attached to our standard types of pressure tanks such as TA, TB series. It can also be attached to TB, TG series depending on certain conditions.
