For the transport of concrete, steel piping and rubber hoses of various lengths and thicknesses are used. In order to meet practical requirements and provide for fast assembly when connecting the pipes for concrete, special couplings are used to close the ends of the pipes which are fitted with special flanges (collars). According to the type of gasket assuring the seal, we can distinguish two main connection systems: 'GU' system (using double lipped gaskets) and 'OR' system (using o-ring gaskets).
Pamec produces both type of system and on request can provide custom tailored modifications.
