Die-Cut Waveguide Gaskets
The gasket must match the flange face, groove and sealing duty. Start with whether you need pressure sealing alone or both RF and pressure sealing, then specify the profile and thickness.

Before you order
Pressure-only or RF and pressure?
Pressure-only seal
The original selection notes specify non-conductive silicone or neoprene, in O-ring or rectangular profiles designed for the flange groove.
RF and pressure seal
The source specifies a conductive gasket when both functions are needed. Conductive fillers described include copper or silver.
Profile and thickness
The table lists thicknesses from 0.5 to 2 mm. Send the aperture, bolt pattern, outside profile and groove dimensions; WR size alone does not define the gasket.
Check the flange size and gasket-fit guide before ordering. The conductive gasket selection guide covers material and profile choices.
For the rest of your setup
Looking for an O-ring profile?
A flat die-cut gasket and a groove-fitting O-ring are different shapes. Compare the gasket and O-ring range if your existing flange uses a recessed seal.

| Note: PRESSURE SEAL; or PRESSURE and RF SEAL ? @If a Pressure seal only, then use a NON-CONDUCTIVE Gasket. These are usually Silicon or Neoprene material, O-rings or Rectangles, designed to fit into flange grooves. @If a Pressure and RF seal is required, then use a CONDUCTIVE Gasket. These look similar to the non-conductive gaskets, but are filled with a conductive material, usually copper or silver. The exception is the Die-cut Gasket, which resembles the flange face. | ||||||||||

Questions before ordering
Can you quote from an existing gasket?
Send its dimensions or a drawing, material if known, thickness and clear photographs of the flange face. Include pressure and temperature conditions.
Does the same WR size guarantee the same gasket fit?
No. The flange face, holes, grooves and seal profile also need to match. Supply the full flange designation or drawing.
