Type Z™ Rotary Unions For thermal oil service Compact double carbon supported bearing union. Engineered reliability and performance.

Overview Type Z rotary unions are designed for thermal oil applications. The union is supported by two internal carbon guides (bearings) and can run up to 500 RPM and 300°C. The proprietary antimony impregnated carbon seal ring is in compression sealing against the stainless steel nipple and seal plate. This seal package combination provides for a long-lasting and low maintenance rotary union. The type Z rotary union is available in sizes from 19 mm to 102 mm with both flanged and threaded connections. Type Z rotary unions are designed for high temperature thermal oil applications.
