A Century by Your Side: Excellence in OEM Gasket Solutions
For nearly a century, Spesso Gaskets has been a trusted Original Equipment Manufacturer (OEM) for high-quality gasket solutions.
Our commitment to precision, reliability, and innovation has earned us the trust of an ever-growing number of OEM customers across Europe.
Our OEM applications range from two-wheeler engines to heavy-duty trucks. We specialize in cylinder head and exhaust gaskets, but we also design and manufacture flat specialty gaskets for engines, compressors, transmissions, and other assemblies. Each product is engineered with advanced materials and state-of-the-art technologies to ensure durability and performance.
Moreover, our ability to adapt quickly to evolving customer needs is a key competitive advantage. We deliver flexibility, premium quality, competitive pricing, and rapid delivery, making us a reliable partner for global OEMs.
Through Lean Manufacturing principles (Toyota Production System), we continually improve efficiency and sustainability. This approach eliminates waste across the entire value stream, creating processes that require less effort, less space, less time, and fewer defects, while maintaining the highest quality standards.
As a result, our OEM business has seen steady growth. In the past 20 years, the share of our Original Equipment segment has expanded from 30% to 70% of total production — a clear sign of our customers’ ongoing trust and satisfaction.

SEALING TECHNOLOGIES

Linear Sealing
The “Linear Sealing Technology” (metallic line) relies on the spring effect of beaded metal plates and is particularly used in the automotive and heavy-duty Original Equipment business.

Surface Sealing
The “Surface Sealing Technology” relies on recovery and compressibility effect on all surface.

Custom Coated Composite
This technology combines a beaded steel core with a custom engineered partial coating.
laboratory and testing
To ensure our customers with the highest quality standards, we carry our several tests on material and gaskets in our internal laboratory.
