The Type YH606 is a rotating seal with all of the same high-strength design features of the Type YH609. In addition, the Type YH606 incorporates drive lugs under the bellows that provide added rotational drive. This reduces tensional stress on the bellows, and makes the Type YH606 the ideal seal for maximum reliability and extended life in viscous or thermosetting applications □ Performance Capabilities Temperature: -75°C/-100°F to 425°C/800°F with Graf oil static packing Pressure: vacuum to 20 bar / 300 psi vacuum to 69 bar / 1000 psi with DOUBLE-PLY bellows Speed: to 50 mps / 10,00 sfpm □ Materials of Construction Bellow: Heat-treated AM350 or Inconel 718 Adaptive Hardware: 300 Series Stainless Steel Faces: Carbon, Tungsten Carbide, or Silicon Carbide Static Seals: Graf oil
