Our Conductive Washers & Disks are precision-cut components designed to provide reliable EMI/RFI shielding and electrical grounding around screws, bolts, connectors, and enclosure interfaces. 

Manufactured from electrically conductive materials, these washers and disks ensure optimal electrical contact while maintaining excellent mechanical sealing performance. They are widely used in electronics, telecommunications, medical devices, industrial equipment, and defense applications.

Available material & thickness

We manufacture conductive washers and disks from the following materials:

  • Electrically Conductive Foam (is especially recommended when lightweight solutions and easy installation are required.)
  • Silver-Plated Aluminium Conductive Rubber (This material is ideal when long-term stability and reliable grounding performance are required.)
  • Carbon-Filled Conductive Rubber (is widely used in industrial electronics and general shielding applications.)
  • Nickel / Graphite Filled Conductive Rubber (This material is commonly used in high-reliability electronic and military applications.)
Material Thickness (mm)
Conductive foam (FOAM) 0.3, 0.5, 0.7, 1.0, 1.5, 2.0, 2.2, 3.0, 3.5, 5.0 (Tolerance of ± 0.1 mm)
Silver plated aluminium conductive rubber (SPA) 0.3, 0.5, 1.0, 1.2, 1.5, 1.7, 2.0, 2.5, 3.0 (Tolerance Up to 3.0 mm +/- 0.15 mm)
Carbon filled conductive rubber (GRA) 1.0, 2.0, 3.0, 4.0, 5.0, 10.0
Nickel/graphite filled conductive rubber (NIG) 0.3, 0.5, 1.0, 1.2, 1.5, 1.7, 2.0, 2.5 (Tolerance Up to 3.0 mm +/- 0.15 mm)
