Electrically conductive gaskets are a critical interface component for circular connectors mounted through panels or bulkheads. When correctly selected and installed, they provide a reliable low‑resistance path between the connector shell and the equipment enclosure, ensuring effective EMI/RFI shielding, electrical bonding, and environmental sealing.

At EMCA Interconnect, we supply a focused range of five conductive gasket series, engineered to suit the most widely used MIL and VG circular connector standards. These gaskets are designed for use with both panel‑mount and jam‑nut connectors where consistent shielding performance and mechanical robustness are required.

When a connector is mounted directly to a painted, anodised, or composite panel, electrical continuity between the connector shell and chassis can be compromised. Conductive gaskets solve this by:

• Creating a controlled, repeatable electrical bond between connector and panel;
• Maintaining 360° shielding effectiveness across the connector interface;
• Compensating for surface irregularities and manufacturing tolerances;
• Supporting EMC compliance in demanding electrical and electronic systems.

In many MIL‑spec and VG‑spec applications, the gasket is a mandatory part of the connector installation to achieve the required shielding attenuation.

When selecting a conductive gasket, the following factors should be considered:

• Connector standard and shell size (MIL or VG series);
• Mounting method (panel‑mount or jam‑nut);
• Required shielding effectiveness;
• Environmental exposure (temperature, vibration, moisture);
• Panel material and surface finish.

Our technical team can support gasket selection alongside other connector accessories to ensure full system compatibility.
