Frabopress 316 Big-Size

FRABOPRESS 316 BIG SIZE is a system of pipes and press fittings made of AISI 316L STAINLESS STEEL for drinking water feeding and distribution systems. It is widely used in both construction and industrial fields thanks to its rust resistance, hygiene, reliability and quickness of installation.

FRABOPRESS 316 BIG SIZE fittings come with a high-performance EPDM O-ring as standard. The high performance and excellent behaviour of this material against ageing, ozone, sunlight, weather, alkaline substances, and a number of chemical compounds allow their safe and durable use in most civil and industrial applications, including the management of steam conveyance systems.

For more detailed information on products installation and fields of application, it is necessary to refer to the technical data sheets available in the DOWNLOAD section of the website.

  • Ideal for the construction of drinking water feeding and distribution systems
  • Corrosion resistance, hygiene and reliability
  • Excellent behaviour of the material against ageing, sunlight, weather, alkaline substances
  • Speed of operation, saving time and offering increased productivity levels
  • Gaskets can be fitted without welding, eliminating the risk of fire in more hazardous situations (working in older buildings, furnished rooms, etc.)
  • No need for dangerous gas pumps or containers, completely eliminating the need to make the connections required by law
  • Elimination of all welding materials, with inevitable cost benefits
  • Junctions free from burning or rings with an excellent immediate visual impact
  • Integrity of pipe insulation thanks to the absence of heat sources
  • Increased wall thickness to ensure the reliability and durability of junctions and fittings
  • Polygon-shaped press designed to ensure maximum resistance to traction and torsion stresses
  • Precision cleaning of internal surfaces to eliminate oily residues due to processing and to ensure protection against rust under all operating conditions
