EMI Shielding Gaskets are specialized, electrically conductive seals designed to block electromagnetic and radio frequency interference across seams, panels, and enclosure gaps in critical systems.
By ensuring continuous electrical conductivity across enclosure seams, these gaskets protect sensitive electronics, prevent false signals, and guarantee accurate, artifact-free operation. They are engineered for demanding environments from MRI imaging suites where diagnostic precision is paramount, to power generator enclosures where electromagnetic noise must be fully contained.

Key Features
Why engineers
specify EMI gaskets
EMI Shielding Gaskets are engineered around the specific demands of environments where electromagnetic interference cannot be tolerated where a single gap in an enclosure seam can disrupt diagnostics, corrupt data, or cause equipment failure in adjacent systems.
Blocks EMI & RFI
Prevents electromagnetic and radio frequency interference from entering or escaping an enclosure protecting sensitive electronics from false signals and ensuring the integrity of the equipment's own emissions.
Continuous Electrical Conductivity
Ensures unbroken electrical contact across enclosure seams, housing joints, and panel interfaces maintaining a complete conductive path that eliminates gaps where interference can leak in or out.
Creates a Faraday Cage
By tightly sealing enclosure seams doors, panels, ventilation vents the conductive gasket creates a continuous electrical barrier. This Faraday cage effect prevents EMI leakage in both directions across the enclosure boundary.
Seals Enclosure Gaps
Generators, MRI housings, and shielded rooms contain doors, panels, and vents where seams act as slots that leak or receive electromagnetic noise. EMI gaskets fill these gaps with a conductive, compliant seal that eliminates the slot antenna effect.
Protects Sensitive Electronics
In MRI environments, radiofrequency waves and strong magnetic fields generated during imaging must be contained. EMI gaskets protect surrounding equipment from these fields while also shielding the MRI system itself from neighbouring interference.
Prevents False Signals & Artifacts
In diagnostic imaging, unshielded interference introduces artifacts into MRI scans compromising diagnostic accuracy. EMI gaskets maintain the electromagnetic integrity of the shielded room, guaranteeing artifact-free imaging results.
Applications
Where EMI gaskets are used
01
MRI Machines & Imaging Suites
MRI scanners generate radiofrequency waves and strong magnetic fields during imaging procedures. These are critical for diagnostic precision, but can disrupt surrounding electronic devices. EMI gaskets are installed across the seams of the MRI system's housing and the surrounding shielded room, ensuring continuous electrical conductivity that blocks interference both in and out protecting nearby equipment and guaranteeing accurate, artifact-free diagnostic imaging.
02
Power Generators
Electrical generators produce high-frequency electrical noise from alternator and engine components. This electromagnetic radiation can leak through enclosure seams doors, panels, and ventilation vents and disrupt nearby sensitive electronics. EMI gaskets seal these gaps, creating a continuous conductive barrier (Faraday cage) around the generator enclosure that prevents EMI leakage from reaching surrounding equipment.

FAQ
Common questions answered
What does an EMI gasket actually do?
An EMI gasket is an electrically conductive seal that maintains continuous contact across enclosure seams. By eliminating gaps in the metal housing, it creates a complete Faraday cage a continuous conductive barrier that prevents electromagnetic and radio frequency interference from passing through the enclosure boundary in either direction.
Why are EMI gaskets critical for MRI machines?
MRI scanners generate strong magnetic fields and radiofrequency waves during imaging. Without proper shielding, these fields can disrupt nearby electronics and external interference can corrupt the MRI signal, introducing artifacts into diagnostic images. EMI gaskets seal the imaging suite and scanner housing to ensure the electromagnetic environment inside remains controlled and interference-free, protecting both diagnostic accuracy and surrounding equipment.
How do EMI gaskets work in generator enclosures?
Generator enclosures contain doors, panels, and ventilation vents. The seams and gaps in these metal housings act as slots that leak high-frequency electrical noise produced by the alternator and engine. EMI gaskets seal these gaps with a conductive material, completing the enclosure's electrical continuity and preventing noise from radiating outward to disrupt sensitive equipment in the vicinity.
What is the "slot antenna effect" and why does it matter?
Any gap or seam in a metal enclosure can act like a slot antenna radiating or receiving electromagnetic energy at frequencies related to the gap's physical dimensions. Even small openings can leak significant interference at certain frequencies. EMI gaskets eliminate these slots by filling gaps with a conductive seal, removing the antenna effect entirely.
Do EMI gaskets also provide grounding?
Yes. Because EMI gaskets maintain continuous electrical conductivity across enclosure seams, they also serve as a grounding path between mating surfaces. This ensures that the entire enclosure remains at the same electrical potential which is essential for both shielding effectiveness and system safety in environments like MRI suites and generator rooms.
