ダイコー Product Lineup

Our company has been processing and selling gaskets, packing, and industrial products for over 45 years. We use various processing machines, including one of Japan's largest water jet cutters (high-pressure cutting machines), plotters, and press processing, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. 【Processing Example】 We recreated a broken part from a beverage manufacturer based on the damaged component and incomplete drawings provided. Although there were some first-time processes, such as machining the seating on both sides, the finish of the cross-section was comparable to that of the original product.

We utilize various processing machines, including one of Japan's largest water jets (high-pressure cutting machines), plotters, and press processing, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. 【Processing Example】 We processed Viton rubber with a thickness of t5. Since the hardness of the rubber is 80°, which is somewhat hard, we reduced the processing speed when using the water jet compared to regular rubber. This time, we set the speed to approximately 1000mm per minute. We also have other thicknesses of Viton rubber in stock, so please feel free to inquire.

The smaller the diameter, the more material rebound occurs, increasing the difficulty of production. When processing as a single piece, it requires processing from a rubber sheet with a thickness of 60mm, and the machines that can handle this are limited. If adhesive processing is possible, we can offer it at a low cost.

Daiko Corporation will answer your questions regarding gaskets and packing. 〇 About RCF (Refractory Ceramic Fiber) Regulations In November 2015, the Specific Chemical Substance Hazard Prevention Regulations were amended and enforced, leading to regulations concerning the handling of RCF. The purpose is to strengthen measures to prevent health hazards for workers related to refractory ceramic fibers. The "Ordinance to Partially Amend the Enforcement Order of the Labor Safety and Health Act" (Ordinance No. 294 of 2015) was promulgated on August 12, 2015, and the "Ministry of Health, Labor and Welfare Ordinance to Partially Amend the Labor Safety and Health Regulations" (Ordinance No. 141 of 2015) was promulgated on September 17, 2015. 〇 Transition to Biodegradable Ceramic Fibers In response to the regulations, we have changed the conventional ceramic fibers to biodegradable ceramic fibers developed to have solubility even when they enter the body. In terms of performance, the only difference is between fibers that dissolve in biological water (RCF-compliant products) and those that do not dissolve (RFC non-compliant products). We guarantee that there are no products that are inferior in performance compared to existing products.

Daiko Co., Ltd. will answer your questions regarding gaskets and packing. "Is it possible to reuse a gasket that has been used once?" → Reuse is not recommended regardless of the usage period or type. Although flanges may appear smooth at first glance, they have microscopic irregularities. A gasket that has been used once deforms to fit the contours of the flange. If this deformed gasket is reused, gaps may form between the flange and the gasket, leading to the possibility of leaks. *For more details, please refer to the PDF document or feel free to contact us.

Daiko Corporation will answer your questions regarding gaskets. "What could be the cause of a leak during a pressure test using a joint sheet?" → (1) The shape is F.F (full face). (2) Stress relaxation (compression of the gasket) has occurred. (1) F.F. gaskets require a greater tightening force compared to F.R. (ring type) gaskets because they have a larger contact area with the flange. A leak may have occurred due to insufficient tightening surface pressure, so we recommend changing the shape to F.R. (2) There is a possibility that the tightening force has decreased due to stress relaxation (compression of the gasket). Please retighten with the initial tightening force. *For more details, please refer to the PDF document or feel free to contact us.

Daiko Co., Ltd. will answer your questions regarding gaskets and packing. "What is the difference between SUS316 and SUS316L?" → There is a difference in workability. SUS316L is a stainless steel that is easier to process than SUS316. SUS316 contains a higher amount of hard metals (Cr, Ni), making it difficult to work with, but by lowering the carbon content, it becomes slightly softer and easier to process. (The "L" stands for low carbon.) The main difference is the carbon (C) content, with SUS316L having "0.03% or less," which falls under the "0.08% or less" of SUS316. *For more details, please refer to the PDF document or feel free to contact us.

Daiko Co., Ltd. will answer your questions regarding gaskets and packing. "What should I use if Teflon is too hard and won't stop?" → We recommend Teflon cushion or soft Teflon. The core joint sheet is soft, making it easy to conform to flanges, which improves sealing performance. Soft Teflon is pure Teflon, so it can be used in processes that are sensitive to impurities. When you actually use it, we will help you select the appropriate gasket, so please feel free to consult us. *For more details, please refer to the PDF materials or feel free to contact us.

Daiko Co., Ltd. will answer your questions regarding gaskets and packing. Products like T9010-A6 and V7030(S) allow for sealing at low surface pressure by sandwiching a soft felt material in the joint sheet to improve sealing performance. However, when used in areas exposed to rain or condensation, the felt can absorb moisture, making it unsuitable. In such cases, it is better to use joint sheets like T9010-A5 or V7030(N) along with products that only have a Teflon coating.

Daiko Corporation will answer your questions regarding gaskets and packing. 〇 Creep Phenomenon It is known that fluoropolymer-based gaskets experience significant decreases in bolt axial force due to creep relaxation characteristics. This reduction in bolt axial force raises concerns about sealing performance, and the risk of leakage accidents increases due to internal pressure loads and external forces from earthquakes, making it necessary to properly manage bolt axial force through re-tightening. 〇 Countermeasure Products We offer gaskets that improve creep resistance by mixing PTFE with special inorganic fillers that have corrosion and heat resistance, suitable for use up to 200°C. Representative products include Vulcan's V7020 and Nichias's T9007LC. They are resistant to almost all fluids except for hydrofluoric acid and strong alkalis. We have stock in sheet form and can process it to your specified dimensions.
