Since seal tape wrapping and liquid gasket application are unnecessary, it improves construction efficiency on site. It prevents inconsistencies in wrapping, insufficient application, and excessive application due to differences in workers' experience.
In the pneumatic joint industry, our pre-coated threaded joints, which hold an 80% market share (according to our own research), are coated in advance with a fluororesin-based sealant on the PT thread section. On-site, these joints demonstrate sealing performance simply by being tightened, using the processed joints. They are effective not only for leak prevention but also for preventing loosening, and due to the fluororesin-based sealant, they also help prevent galling. *If you are interested in information regarding our adoption results, please feel free to contact us.

basic information
Pre-coated threaded joints are products with stable quality, as a fluororesin-based sealant is applied to the PT threaded section in advance using a coating machine, allowing for management of the application amount and width. ◎ Since there is no need for sealing tape wrapping or liquid gaskets, on-site construction efficiency is improved. ◎ Uniform quality control is possible with a dedicated coating machine, preventing contamination and defects caused by uneven sealing tape application, as well as insufficient or excessive application of liquid gaskets leading to leaks. ◎ Reduction and simplification of work time, leading to increased productivity. ◎ Excellent pressure resistance, oil resistance, and chemical resistance. (Some fluids may be unsuitable.) * We also offer sealing processing of supplied materials, sealing processing including joint base materials, as well as the sale of sealants and dedicated coating machines (in-house production). Please feel free to consult with us.
