M83528/002 EMI O-Rings
Standard Sizes

SSP makes M83528/002 EMI O-Rings from MIL-DTL-8328 Type A, B, C, D and K materials that are part of the Qualified Products List (QPL) from the U.S. Defense Logistics Agency (DLA).

SSP’s M83528/002 EMI O-rings provide alternatives, or offsets, to Parker Chomerics CHO-SEAL and Nolato Jabar products. We have faster lead times and lower minimum order quantities than you’ll find elsewhere, and you can buy from us directly instead of through distributors. 

Whether you need ready-to-fabricate EMI shielding silicones or ready-to-install EMI gaskets, SSP’s materials and products are proudly Made in the USA. Contact us for a quote and let us know what you need.

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.
