MIL-DTL-83528 EMI Silicones and M83528/002 EMI O-Rings

SSP makes M83528/003 O-Rings from EMI/RFI shielding silicones that are part of the M83528 Qualified Products Lists (QPL) from the U.S. Defense Logistics Agency (DLA). SSP’s Type A, B, C, D, and K elastomers provide offsets to Parker Chomerics CHO-SEAL and Nolato Jabar products. Whether your volumes are large or small, we offer a choice of fabrication methods.

  • For higher volumes, SSP uses die cutting to convert sheets or continuous rolls.
  • For prototyping and lower volumes, SSP offers flash cutting and compression molding.

As a vertically integrated manufacturer, SSP has it own toolroom so that we don’t have to wait for outsourced molds, tools, jigs, or fixtures. The following section describes the MIL-DTL-83528 Certified materials that we offer.Ā
