Recently, Daiko Co., Ltd. has been featured in the "Job Book for Junior High School Students," which is published as a supplementary educational material for "Career Education" promoted by the Ministry of Education, Culture, Sports, Science and Technology. This publication is a career education support booklet created to convey the significance of work and the appeal of local businesses to junior high school students in the community. In Daiko's section, we provide an easy-to-understand explanation for students about the role of "gaskets and packing," which quietly supports everything from everyday life to industry, as well as insights into the manufacturing field.

Recently, Daiko Co., Ltd. has published a job support book for high school students titled "Start! (Osaka Prefecture Edition 2026)" and has included company information on the related career education support website "Job Start." In this publication and on the site, the role of "gaskets and packing" in supporting social safety, our well-equipped facilities, and interviews with young employees active on the front lines are detailed, showcasing the appeal of Daiko's manufacturing.

Our company, Daiko Co., Ltd., was featured on the information program "Asasuma!" which airs every Sunday at 9:30 AM on Sun TV! The program thoroughly covered Daiko's technology in the manufacturing and sales of various gaskets and packing essential for infrastructure equipment and industrial machinery, as well as our commitment to solving customer challenges.

This is a reference document for practitioners to solve challenges such as 'Which material should I choose for safety?' and 'I don't know which gasket fits the fluid conditions.' Please download it for your consideration.

Are you having trouble selecting gaskets and packing? With the transition from asbestos to non-asbestos, it has become difficult to choose the right type. We have compiled a list of products from various manufacturers that correspond to different fluids, and we hope you can use it as a guideline for selection.
