This rotary union incorporates the latest technology in mechanical seal design for water and thermal oil service. The high thrust load capability and carbon-to-silicon (or Tungsten) carbide seal package makes the RX rotary union run longer and with less maintenance requirements that other ball bearing designs. All O-rings are fully captured in glands and seal-loading springs do not contact the process fluid. The RX rotary union features a barrier in the seal chamber to extend bearing life and a nipple and assembly plate made of stainless steel. Available in single- and dual-flow configurations and sizes from 3/8” to 6”, the RX rotary union is capable of operating up to 500°F (260°C), 150 psig (25 bar), and 3,500 rpm.
