How to choose a suitable waveguide gasket and O-ring to connect two waveguide flanges? This is one of the most frequently asked questions by customers. The following information will help you.
Function:
1: What is the role of gaskets in your application…
2: Pressure sealing; or pressure and RF sealing?
a: If pressure sealing only, use non-conductive gaskets.
These are typically silicone or neoprene materials, o-rings or rectangles designed to fit into flange grooves.
b: If pressure and RF sealing are required, use conductive gaskets.
These look similar to non-conductive washers, but are filled with a conductive material, usually copper or silver. One exception is die cut gaskets, which are similar to flange faces.
Before choosing, you need to know:
1: Waveguide size
2: The type of flange to be used
3: Function: Pressure only [non-conductive] or pressure and RF sealing [conductive]
