Socket Fusion System

Socket fusion tools

Socket Fusion System Hermetically seals Polypropylene and PVDF Pipe and Fittings for Pure Process Water and Chemical Waste Drainage Systems

Systems using polypropylene (PP) or polyvinylidene fluoride (PVDF) piping are durable, strong, and tamper-proof. Heat fusion forms a complete hermetically sealed system, which makes socket fusion ideal for severe usage applications.

Socket fusion type pipe and fittings are joined by heat fusing the PP or PVDF material with an Orion thermostatically controlled heat tool. In a semi-molten state, pipe and fittings are easily joined to form a strong and permanent sealed joint. PVDF fittings and pipe are also available in the socket fusion joining system, however, PVDF and PP will not fuse together because they are dissimilar materials.


  • Completely sealed for strength and durability
  • Forms true hermetically sealed joint
  • All identical material, no electrolysis, no metal in joint
  • Ideal for severe use applications
  • Meets ASTM D2657 standards in its entirety
