  • High-ductile iron casting for superior heat-cycle durability. Pressed hydraulic joints for a leak-free seal across all temperature ranges. 

  • High-density green-sand cores for optimized port geometry and smoother flow. 

  • CNC-machined gasket & turbo surfaces ensure true flatness and easy sealing. 

  • Reinforced gussets in high-stress zones for added strength.
