Gasket Packing Q&A No. 1

We will answer your questions about the reuse of gaskets!

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.
