Towards even higher temperature and corrosion resistance. Gaskets suitable for zero asbestos in environments with operating temperatures above 800°C.
The "NAPI-816 series" is a gasket that uses zero-asbestos board with a heat resistance of 1000°C for the internal material and heat-resistant, corrosion-resistant stainless steel (SUS316L) for the external material. Additionally, we can manufacture products that exceed the heat and corrosion resistance limits of conventional gaskets using materials such as nickel-based super alloys (NAPI-1200) and titanium (NAPI-800TI). We also offer the "NAPI-900/1200 series." Please consult with us for the production of oversized gaskets that are outside standard specifications. 【Features】 ■ High-temperature exhaust corrosion resistance and high-temperature use ■ Suitable for zero-asbestos applications in environments with temperatures above 800°C ■ Internal material uses zero-asbestos board with a heat resistance of 1000°C ■ External material uses heat-resistant, corrosion-resistant stainless steel (SUS316L) ■ Capable of producing oversized gaskets that are outside standard specifications *For more details, please refer to the PDF document or feel free to contact us.

Company information
Asbestos testing in Japan is conducted using the JIS method, which employs "X-ray diffraction" and "phase contrast and dispersion microscopy." However, this method has been criticized for its flaws, such as misidentifying other particles as asbestos and potentially missing asbestos content below 5%. Therefore, even products deemed non-asbestos in Japan may be determined to contain asbestos when tested using the polarized light microscopy (PLM) method, which is recognized as a more reliable method in Europe and the United States. To avoid such situations, a standard called "Zero Asbestos," which ensures that products contain no asbestos and have passed inspections using polarized light microscopy (PLM) and even more reliable electron microscopy, is gaining traction. In July 2012, an ISO asbestos analysis method was published, and the JIS method was excluded, accelerating this movement domestically. In anticipation of this trend, our company has obtained the trademark for "Zero As" and has promptly introduced inspections using polarized light microscopy and electron microscopy. Since 1990, all our products have been certified as Zero Asbestos, so please use the "Zero As Gasket NAPI Series" with confidence.
