The Rotaseal 4000L Series is a double-fluid passage rotary joint developed for air, hydraulic oil, coolant brake fluid, and vacuum applications. Available in sizes ranging from 1/2” (DN 15) to 1” (DN 25), this model offers high-pressure resistance and fluid management efficiency thanks to its tandem design.
The radial body entries and bearing system provide long-lasting performance with low friction, while the aluminum body and hard chrome-plated stainless steel shaft ensure extra durability against wear and corrosion. The FKM O-ring PTFE seal offers excellent sealing and high-temperature resistance.
With its self-supporting compact design, the 4000L Series enables easy installation and provides reliable and efficient operation, making it an ideal choice for demanding applications.
