TechMESH Knitted-Wire Gaskets for Rugged EMI/RFI Protection
Reliable EMI/RFI performance for demanding enclosures and fast-moving electronic systems.
Versatile knitted-wire options engineered to meet the demands of high-frequency, high-reliability systems.
In modern enclosures, performance alone isn’t enough — you need materials that stay stable under mechanical stress, thermal expansion, and changing electrical conditions. TechMESH knitted-wire gaskets are engineered to meet these demands with a structure that adapts to uneven surfaces, maintains conductivity under vibration, and delivers repeatable performance across a wide frequency range. Whether you’re sealing access panels, protecting sensitive circuits, or managing EMI/RFI in harsh environments, TechMESH provides the mechanical resilience and electrical reliability today’s designs require.
Below are the core configurations available in the TechMESH family, each engineered to support different enclosure requirements and operating conditions.

How TechMESH Works
TechMESH is engineered from interlocking metal loops that form a flexible, three-dimensional knitted structure. When compressed between mating surfaces, these loops behave like miniature springs — deflecting smoothly, distributing force evenly, and returning to their original shape once pressure is released. This spring-like behavior is what allows TechMESH to deliver consistent mechanical performance over thousands of compression cycles.
Because each loop is in constant electrical contact with adjacent loops, the mesh forms a dense network of conductive pathways. As the material compresses, these contact points increase, creating a tighter, more continuous shielding barrier. This allows TechMESH to maintain electrical conductivity even when installed in housings that experience vibration, impact, or structural flex.
Unlike rigid metal gaskets, the knitted-wire structure adapts naturally to irregular or uneven interface surfaces. It fills micro-gaps, conforms to slight misalignments, and compensates for manufacturing variances in enclosure hardware. This flexibility also enables effective EMI/RFI attenuation across a wide range of frequencies, especially in environments where surfaces may shift over time due to thermal cycling or mechanical stress
