REX N-Series is a rod-supported version of REX joints. It is a specialized variation, designed for use where an internal inlet or outlet pipe must rotate with the roll on paper machine dryers with rotary syphons, double shell dryers, rotary steam tube dryer and similar machines. The N-Series REX Joints can accommodate a rotating syphon or distribution pipe as an integral part of the rotating assembly.
Nipple and thrust collar keyed together, rotate against carbon graphite seal rings. Thrust collar serves as packing box to prevent leakage along inner pipe; however, rotates as a unit, Seal between stationary and rotating part does not rely on any packing. Spring is for initial seating only; in operation joint is pressure sealed. They are available in sizes from 1½” to 6”. Standard series joints are suitable for pressure up to 150 PSI.
