M83528 Slash Size for EMI Military Gaskets

M83528 slash sizes provide a standardized framework that ensures EMI military gaskets deliver consistent, repeatable performance across defense and aerospace platforms. By understanding how each slash sheet defines material properties, filler systems, and gasket geometries, engineers can confidently select the right conductive elastomer for their application. 

Specialty Silicone Products (SSP) fabricates EMI military gaskets and O-rings from the the MIL-DTL-83528 QPL certified silicones that we produce at our Made in USA manufacturing facility. Compare our materials and products to Parker Chomerics CHO-SEAL and Nolato Jabar. SSP offers low minimums and quick turnarounds. 

EMI Military Gaskets in M83528 Slash Sizes

By selecting the correct slash size, engineers ensure that the EMI military gasket will:

• Fit the intended connector or enclosure
• Deliver the required shielding effectiveness (often 100 dB or more)
• Maintain sealing performance under vibration, temperature cycling, and humidity
• Meet the mechanical tolerances required for military hardware

Understanding M83528 Slash Sizes (Part Numbers)

The MIL-DTL-83528 specification establishes the following structure for part identifying numbers (PINs). 

• Military designator (M)
• General specification number (83528/)
• Specification sheet number (3 digits)
• Material type (A to M)
• Dash number (001 and up)

Military Designator

The military designator is always M

General Specification Number

and the general specification number is always 83528/.

Specification Sheet Number (3 Digits)

The three-digit specification sheet number indicates the type of product from which the EMI gasket is fabricated, or the type of gasket that is produced. In the bulleted list above, 001 indicates that the gasket is made from Solid Cord.

Material Type

For each M83528 PIN that SSP fabricates, the material type is A, B, C, D, or K, depending on the type of MIL-DTL-83528 silicone that’s used.

Dash Number

The dash number (after the /) indicates the EMI gasket’s nominal dimensions, which are defined in separate tables for each of the 14 categories listed above.

Provided dimensions vary by gasket type. For example, solid rectangular gaskets have nominal dimensions for width and height.

Sample M83528 Part Number

Together, the elements of a M83528 PIN describe the characteristics of the EMI gasket. For example, M83528/009A001 indicates the following:

• The EMI gasket is for military application (M).
• It meets MIL-DTL-83528 requirements (83528/).
• The shape is a solid rectangle (009).
• The gasket made of a MIL-DTL-83528, Type A material (A).
• Based on the dash number (001), the width is .063 mm and the height is .042 mm.
