The Rotaseal 420 Series rotary joint, available in sizes from 1/4” (DN 08) to 3/8” (DN 10), is specifically designed for coolant fluids. Its single-fluid passage design, combined with axial and radial body inlets, offers flexible mounting options while the self-supporting design ensures superior durability.
The dry running without pressure feature minimizes maintenance requirements, while the aluminum body and stainless steel shaft and spring provide high resistance to corrosion. The bearing-protective labyrinth structure and balanced sealing system deliver long-lasting and reliable performance for various applications.
The 420 Series offers a robust, efficient, and low-maintenance solution for handling coolant fluids effectively.
