FLUID HANDLING RX® Rotary Union /8” to 11/2” Single and Dual Flow The RX rotary union connects stationary piping to a rotating device. The fluid is sealed by precision, micro-lapped seals that provide a uniform, full-flow design. The union is supported by two widely-spaced anti-friction bearings and is available with a bearing isolation system for added bearing protection. The RX union is capable of intermittent dry running and features a 100% pure-molded carbon graphite or silicon carbide seal and tungsten carbide counterseat. Standard RX Ratings Pressure: Speed, straight thread: Consult Kadant Johnson for RX-1, RX-2, and RX-3 unions for applications up to 450°F (232°C).
