Gasket Packing Q&A No. 5

What is the difference between Teflon cushions with felt and those without felt?

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.

Gasket Packing Q&A No. 7

Have regulations been established for ceramic fiber-related products?

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.

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 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 Examples】 We cut a neoprene rubber sheet to the required length using a water jet and processed it into a cylindrical shape with adhesive. 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.

Gasket Packing Q&A No. 13: What is compression failure of a seat?

What is the compressive failure of a joint sheet?

There are several issues with joint sheets, but I will explain the most common case, which is compression failure. ◆Details of the problem  〇Cracks occurred around the gasket, making it extremely thin. ◆Possible causes  〇Compression failure due to excessive tightening.  〇Excessive load applied to a part of the gasket due to lack of parallelism of the flange or deformation.  〇Localized slippage of the joint sheet due to uneven application of paste. ◆Countermeasures  〇Tighten without exceeding the allowable tightening surface pressure of the gasket.  〇Problems caused by improper construction such as single-sided tightening, insufficient tightening, or excessive tightening.  〇Correct the parallelism and deformation of the flange.  〇When applying paste, apply it thinly and evenly.
