EMI Waveguide Gaskets

SSP molds and cuts EMI waveguide gaskets from the electrically conductive silicones that we make.

We manufacture all of our EMI elastomers in-house. Many have been independently tested to MIL-DTL-83528 and some are QPL listed.

SSP also offers a full certificate of analysis (COA) for each batch of EMI silicones that we make.

In addition, because we have our own toolroom and machinists, SSP makes molds, dies, jigs, and fixtures. 

For standard or custom EMI  gaskets, SSP is your alternative to Parker Chomerics CHO-SEAL materials.  

MIL-DTL-83528 EMI Waveguide Gaskets

SSP makes MIL-DTL-83528 EMI waveguide gaskets in the shapes, cross sections, sizes, and materials that are listed in the tables below. 

Rectangular EMI Waveguide Gaskets: D-Shaped Cross Section

Rectangular EMI waveguide gaskets with a D-shaped section gaskets come in five different sizes. They’re ideal for use with rectangular connectors.  These M83528 gaskets can be molded out of standard compounds and used with or without a groove. Additional sizes available.
