Spira has been serving the EMC community with quality engineered Electromagnetic Interference (EMI) and Radio-Frequency Interference (RFI) shielding products since 1978.

We proudly offer the finest and most reliable EMI/RFI shielding gaskets and honeycomb filters on the market, at very competitive prices. The strength of Spira lies in our exceptional products, on-time delivery, superior customer service, and technical support.

Spira was founded by George Kunkel, an EMI/EMC design engineer, who was frustrated with the problems he encountered with EMI gaskets that were commercially available for EMI/RFI shielding applications. To best address his and the industry's needs, he designed and patented the spiral EMI gasket and developed a whole family of exceptional EMI products.

Spira is committed to manufacturing quality products to ensure that you, the customer, will be able to make an informed decision and choose the best gasket for your design. Each product manufactured by Spira fills a very specific need in the market, not found in any other EMI gasket.
