    To make a leak tight UHV seal between two conflat flanges, a gasket is required. Our gaskets are manufactured from quality controlled precision sheet material.


    Leak Valves

    Leak valves are used to very accurately control the flow of gas into a vacuum system from an external source. They utilise the basic sealing principle of the all metal angle valve - namely a softer metal pad forced against a harder metal seat.
