Improved work efficiency on-site as sealing tape winding and liquid gasket application are unnecessary. Prevention of uneven winding issues due to differences in workers' experience.
Isn't it a hassle to wrap seal tape around joints? Doesn't wrapping seal tape create inconsistencies depending on the craftsman? Would you like to prevent liquid leakage more easily? The Eight Seal 'Pre-coated Screw Fittings' are coated with a specialized fluorine-based sealing agent on the threaded parts, eliminating the need to use seal tape or liquid sealants on the job site to prevent fluid leakage. Additionally, since the specialized fluorine-based sealing agent is directly applied to the joints, issues caused by uneven wrapping by workers do not occur. Feature 1: Adhesion It is non-fusible at high temperatures, retains elasticity at low temperatures, and exhibits high sealing hardness. Feature 2: High Durability It has excellent pressure resistance, oil resistance, and chemical resistance, maintaining its effectiveness even after long-term storage. Feature 3: Labor Saving By eliminating the need to wrap seal tape, it reduces labor hours and does not require specific skills from workers. If you specify the screws and joints you wish to have sealed, we can deliver them as processed products! Please take this opportunity to try it out! (Free samples are available!)
