Since PTFE is used as a filler, it is particularly suitable for sealing highly permeable fluids and gases.
A spiral wound gasket is a gasket that is formed by winding a metal strip shaped like a V, called a hoop, around a filler material, known as a cushioning material, while overlapping them, and fixing the beginning and end of the winding with spot welding.

basic information
Since the filler uses PTFE, it is particularly suitable for sealing highly permeable fluids and gases. Additionally, PTFE has excellent chemical resistance, making it suitable for sealing corrosive fluids. (Please pay attention to the material of the hoop when using it with corrosive fluids.) The basic spiral gasket is primarily used with fitting-type flanges or groove-type flanges, with the diameter of the gasket portion only. *The hoop can be manufactured in metals other than SUS304 depending on the usage conditions. Please consult us.

Company information
In the year 1907, during an era still dominated by a preference for foreign products, Ohno Company developed Japan's first packing for ships. It was recognized by both Mitsubishi and Kawasaki shipyards and was of such high quality that it was later used in the former navy's battleship Yamato, breaking the common belief at the time that domestic products were inferior to imported ones. Since then, we have continued to focus on our core business by adopting new materials such as fluororesin and super engineering plastics, developing processing technologies, and establishing a quality assurance system through obtaining ISO 9001 certification, all while responding to market and customer demands with a serious commitment to manufacturing. We will continue to maintain a spirit of challenge, value our customers and quality, and contribute to a new society. We have factories in Kobe City, Hyogo Prefecture, and Sasebo City, Nagasaki Prefecture, as well as sales offices in Tokyo, Osaka, Kobe, and Sasebo.
