Towards further ultra-high temperature and ultra-corrosion resistance. Gaskets suitable for zero-asbestos in environments with 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 Ni-based super alloys (NAPI-1200), titanium (NAPI-800TI), and others. We also offer the "NAPI-900/1200 series." Please consult us for the production of large 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 ■ Uses zero-asbestos board with a heat resistance of 1000°C for the internal material ■ Uses heat-resistant, corrosion-resistant stainless steel (SUS316L) for the external material ■ Capable of producing large 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 considered more reliable in Europe and the United States. To avoid such situations, a standard known as "Zero Asbestos," which ensures that products contain no asbestos and have passed tests 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 testing using polarized light microscopy and electron microscopy. Since 1990, all of our products have been certified as Zero Asbestos, so you can use the "Zero As Gasket NAPI Series" with confidence.
