The Rotaseal 4000D Series is a high-performance rotary joint optimized for air, hydraulic oil, coolant brake fluid, and vacuum systems. Available in sizes from 3/4” (DN 20) to 1-1/2” (DN 40), this model features a double-fluid passage design for superior performance.
The bearing system ensures long-lasting and trouble-free operation, while the lightweight and durable aluminum body offers resistance to wear and corrosion. The hard chrome-plated stainless steel shaft delivers high strength, and the FKM O-ring PTFE seal provides exceptional sealing and chemical resistance.
With drain holes and a self-supporting design, the 4000D Series guarantees safe, efficient, and reliable operation in demanding environments.
