Marine Adaptors

  • The Marine design allows angular movement, which caters for minor misalignment and pipe deflection with couplings up to 6º & flange adaptors to 3º. 
  • Marine products up to DN300 are pre-assembled allowing quick and efficient installation, without the need for dismantling, even in the most difficult of conditions.
  • Marine couplings are capable of accommodating 10mm of expansion/contraction per fitting, flange adaptors 5mm which reduces the need for supplementary expansion joints or bellows.
