بست FGR or Staube Flex 3


FGR Flex 3 pipe coupling is featuring an extra wide band is an axial non-restraint coupling used to connect metal and/or plastic pipes quickly and safely.

Advantages: Easy and quick to assemble, Pipe end distance up to 65 mm possible


FGR Pipe Coupling are economical alternative to conventional pipe joining techniques for both plastic and metal pipes. All plain – ended pipes can be joined easily by hand. The ready-to-fit coupling is pushed over the pipe ends and then aligned and rotated to any fitting position. Tightening the two bolts alternately with a torque wrench is all it takes to make a safe fitting.

FGR Pipe Coupling is a reliable connection for thick- and thin- and walled pipes which conforms to the latest DIN standard 86128. Feed and return lines for liquids, gases, and solids (for mechanical engineering and construction, civil engineering, shipbuilding, pipeline construction, power stations, mining, filters, water technology, etc.) are joined quickly, easily and safely using FGR pipe couplings.
