Waveguide Gasket, Die Cut
Dolph Microwave’s Waveguide Gasket, Die Cut provides precision RF/pressure sealing for WR10 to WR2300+ waveguide systems. Engineered in conductive (85 Durometer silver-copper silicone) or non-conductive materials (silicone/neoprene), these gaskets ensure EMI shielding and vacuum integrity while exceeding MIL standards for CPR, UG, CMR, and custom flanges.
Product Description:
Dolph Microwave delivers high-performance die-cut waveguide gaskets engineered for seamless connectivity in rectangular and double ridge waveguide systems. Designed to exceed MIL standards, our gaskets ensure superior EMI/RFI shielding and ultra-high vacuum (UHV) compatibility. Available in WR10 to WR2300+ sizes, they provide critical RF/pressure sealing with attenuation as low as 0.02 dB across 0.5–110 GHz bands. Engineered for aerospace, defense, and telecom applications where signal integrity is non-negotiable.
Key Product Advantages
- Material Expertise: Conductive silver-plated copper silicone (85 Durometer) for EMI shielding, plus non-conductive options (silicone/neoprene/EPDM) for pressure-only sealing.
- Universal Flange Compatibility: CPR, UG, CMR, UDR, UAR, PBR, and custom flange designs (IEC/EIA standards).
- Critical Environment Ready: Withstands UHV conditions (-10⁹ Torr), extreme temperatures (-55°C to +200°C), and vibration.
- Dual-Function Sealing: Choose conductive gaskets (RF + pressure seal) or non-conductive (pressure-only O-rings/half-gaskets).
- Reduced Height Support: Specialized solutions for half-height/reduced waveguide configurations.
Industry Applications

| 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. |
