Product Details

  • Uses aromatic hydrocarbons, gasoline, refined petroleum products, most chemicals and solvents, high temperature air
  • The Fastite joint sealing component – a molded synthetic rubber ring gasket of two hardness, shaped to fit the configuration of the gasket socket
  • The smaller end of the gasket is of harder rubber, approximately 85 durometer hardness, which provides a strong shoulder for self-centering on the gasket buttress, a permanent seal against cold flow, and protection from deterioration
  • The larger end of the gasket is of softer rubber, approximately 65 durometer hardness, providing ease of assembly and positive sealing
  • The design assures effective sealing at low or high pressures and in straight or deflected joint alignment
  • It also eliminates any concerns of infiltration or root intrusion, and assures positive sealing against negative pressure, thus preventing gasket “pullout” should a vacuum be created in the line
  • A taper on the inside of the gasket allows the entering pipe to locate and center on the hard section and reduces friction loads during subsequent assembly
  • The snug fit and the hard section of the gasket, in conjunction with the design of the buttress, act to restrain the gasket against dislodgment during assembly
  • Additional internal pressure results in increased tightness of the seal when pipe is either in straight alignment or deflected
