Coated with fluorine-based sealant! It provides a speedy and reliable connection.
The "CK Pre-Seal 20K" is a 20K fitting for fire extinguishing piping that has been pre-coated with a fluorine-based sealing material. Thanks to the lubricating effect of the sealing material, it reduces the tightening torque and is compatible not only with cutting threads but also with rolled threads that excel in seismic resistance. It eliminates all the cumbersome coating tasks that previously relied on the experience of workers, providing a speedy and reliable connection. 【Features】 ■ All types of 20K fittings for fire extinguishing piping are pre-coated with fluorine-based sealing material. ■ The sealing material is automatically applied in a quality-controlled factory, ensuring stable construction quality. ■ Compatible with piping sizes from 25A to 125A. ■ The outer coating resin is transparent, allowing for easy management of excess threads in buried piping. ■ Made from environmentally friendly materials. ■ The use of transparent resin allows for visual confirmation of the rubber ring installation during construction. *For more details, please refer to the PDF document or feel free to contact us.

Company information
"Where it is said to be impossible, there lies the possibility." The fittings branded with the CK logo are filled with various trials and errors. For example, the development of new materials that are friendly to people and the Earth is one of them. In the "Piping Equipment Business" division, we have developed and commercialized fittings such as "PVC-free" and "lead-free," as well as the world's first "cadmium-free" fittings. Additionally, in the "Hot-Dip Galvanizing" division, we developed the world's only hot-dip galvanized coating, "CKe coating," which does not contain lead or cadmium, and it has also been registered in the Ministry of Land, Infrastructure, Transport and Tourism's new technology information provision system, "NETIS." We have successfully mass-produced the world's first RoHS-compliant fittings using this technology for surface coatings, continuously creating new products as a leading company in the industry. With unique technologies that are not found in other companies, we are bringing the world's first products to market. CK Metal's manufacturing spirit continues to pursue new possibilities with "environment" as its theme.
