The VOSSForm^SQR nut with integrated seal and metric thread, designed for DIN 2353 couplings type MVF, ensures maximum reliability and durability in demanding hydraulic applications. Available in both L (light series) and S (heavy series), it offers versatile compatibility with a wide range of systems. Manufactured from high-quality carbon steel and finished with an advanced zinc-nickel coating of 6–10 µm, the nut provides exceptional protection against wear and corrosion, withstanding up to 720 hours in salt spray testing without visible damage. The use of a Viton seal guarantees excellent resistance to high temperatures, aggressive media, and long-term operational stress, making it an ideal choice for industries where safety and performance are critical. This combination of robust materials, innovative surface treatment, and precise engineering ensures a secure, leak-free connection, extending the service life of hydraulic installations and reducing maintenance costs.
