The Daiko Teflon Cushion Gasket 'D7000' features a Teflon outer layer and uses a joint sheet and heat-resistant milboard as the core material, providing excellent elasticity and flexibility. Thanks to the stable corrosion resistance of Teflon (fluororesin), it can be used with a wide range of corrosive fluids such as acids, alkalis, and organic solvents. Additionally, it has excellent electrical insulation properties and can be used as an insulating gasket for anti-corrosion piping. 【Features】 ■ Excellent chemical resistance ■ Usable over a wide temperature range from low to high temperatures ■ Provides cushioning and high sealing performance compared to pure Teflon ■ Improved creep reduction and stress relaxation at high temperatures compared to pure Teflon, ensuring stable sealing performance *For more details, please refer to the PDF document or feel free to contact us.

At Daiko Co., Ltd., we handle a variety of "Teflon-based gaskets." The "pure Teflon" is a gasket made from punched Teflon (PTFE). It has excellent chemical resistance and also features outstanding electrical insulation properties. In addition, we offer products such as "Teflon sand," which uses a heat-resistant millboard as the core material and has PTFE as the outer layer, providing excellent elasticity and flexibility, as well as "filled Teflon" and "soft Teflon." 【Features】 < Pure Teflon > ■ Gasket made from punched Teflon (PTFE) ■ Excellent chemical resistance and electrical insulation ■ Operating temperature range: -50 to 100℃ ■ Maximum operating pressure: 1MPa (10kgf/cm²) *For more details, please refer to the PDF document or feel free to contact us.

This is a gasket made from Daiko's "D Packing (EPDM molded packing)" rubber, which is pressure-formed into a cross-sectional shape. For areas requiring chemical resistance and corrosion resistance, we also offer PTFE-coated products that are integrally bonded with PTFE! This packing material provides stable sealing performance at lower surface pressure compared to punched rubber sheet gaskets. (Characteristics) - Being a molded product, it has no uneven thickness and a smooth surface. - The presence of two O-ring shaped protrusions ensures no leakage even at low surface pressure. - The hardness of the rubber is appropriately adjusted to buffer thermal stress and piping stress. - Made from high-quality virgin rubber, it has a long lifespan. - It can also be used with resin and resin-lined flanges. (Supported Sizes) 5K 15A~300A 10K 15A 300A (Operating Temperature Range) -40℃~ 100℃ For sizes above 350A, rubber punched products will be used. (Maximum Operating Pressure) 0.98MPa (approximately 10kgf/cm²)

The "D Packing" we handle is a gasket made by press-molding EPDM rubber into a specific cross-sectional shape. Its structure, featuring two O-ring shaped protrusions, demonstrates excellent sealing performance even at low tightening surface pressures. It can also be used with resin flanges and resin-lined flanges. Additionally, we offer the "D Packing PTFE Coated," which is made by press-heating and molding a PTFE film onto EPDM rubber molded products to create a bonded unit. 【Specifications】 ■ Maximum operating pressure: 0.98 MPa (approximately 10 kgf/cm³) ■ Operating temperature range: -40℃ to 100℃ ■ Available sizes: - 5K: 15A to 300A - 10K: 15A to 300A *For more details, please download the PDF or feel free to contact us.

"I want to select a reliable gasket for a line handling acids and alkalis." "There are concerns about long-term corrosion resistance with gaskets for utility use." To address the sealing challenges in such chemically corrosive environments, Nichias Corporation has developed a fluororesin gasket specialized for chemical resistance, the "TOMBO No.1133" (Clean Silk Clean). In this article, we will thoroughly explain why No.1133 exhibits superior chemical resistance that sets it apart from conventional gaskets, including its structural secrets, specific data supporting its performance, and the correct knowledge for safe usage, all from a professional perspective. *For detailed content of the column, please refer to the related link.

Pure fluoropolymer (PTFE) gaskets are widely used in many chemical lines due to their excellent chemical resistance. However, conventional PTFE sheets have a significant challenge: they are prone to "creep (stress relaxation)" and lack long-term sealing stability. To overcome this weakness, Nichias Corporation has developed the "TOMBO No.9096-SGM" (SGM gasket) using special manufacturing technology. This article thoroughly explains the performance of this "high-strength stretched PTFE gasket," which overturns the conventional wisdom of PTFE, as well as important considerations to maximize its capabilities. We aim to assist field engineers and maintenance personnel in solving sealing challenges under more severe conditions. *For detailed content of the column, please refer to the related links.
