EMI Waveguide Gaskets

EMI Waveguide Gaskets

SSP fabricates EMI waveguide gaskets from the electrically conductive silicones that we make. Many are MIL-DTL-83528 compliant and QPL listed.

We offer a certificate of analysis (COA) with each batch of materials and have an in-house lab and toolroom.   

SSP also makes EMI silicones and waveguide gaskets for civilian applications. 

This includes rectangular waveguide gaskets for UG, CPR, and CMR flanges in EIA waveguide sizes. 

For EMI silicones in low volumes, SSP is your alternative to Parker Chomerics CHO-SEAL materials.
