• TW-Couplings, Tankwagen-Kupplung

  • We provide quick-disconnect TW-couplings for charge and discharge hoses attached to road tankers. They are produced in basically hot-stamped brass alloy, aluminum alloy and stainless steel materials.
  • TW-couplings are available as MK MKS VK VKS MB & VB in the range of DN50, DN80 & DN100. Screw-on fittings, or LNC couplings are usually offered in package which is used for rubber hose assemblies, together with the reuseable DIN clamping system as safety clamps.
  • The series are made according to basically German EN/DIN standards or tailered dimensions per specific demands for equipments. The interchangeability with those from high-profiled companies like 'Elaflex' is out of question.
  • Definite "EN 14420-6"

  • 100% interchangeable with high-profiled Flex-company
    Persistence in quality hikes as fully in compliance with DIN Standard
  • Strategic Quality Hikes

  • TW-couplings are designed and manufactured in compliance with German standard DIN EN 14420-6.
  • The compliance of the Norm is of top priority as the couplings are commonly used to deal with flammable liquids. Leakage from "awkward" connections and "less-than-perfect" joints is likely to cause unmeasureable casualties.
  • Unfortunately the market witnesses a price-oriented quality slide which has been pushing the manufacturers' button to make sacrifice in terms of dimensional and material-involved correctness for survival.
  • Patrol inspection with a special caliber is made randomly on the wellness of 'MK' couplings.Patrol inspection with a special caliber is made randomly on the wellness of 'MK' couplings.
  • In contrast SME has been making continuous efforts for the couplings to achieve full compliance with both the EN Norm and to be interchangeable with the well-recognised market names like 'Elaflex'.
  • We are in the faith that our strategic persistence on quality hike will pay off in the long run.
  • Lots of tailer-made calibers
  • Special cabliers are designed and tailer-made according to EN 14420-6 standard requirements. They are developed per all sizes 2" to 4", for female and male couplings, blind caps and dust plugs respectively.
  • Type test is carried out when torn-out mold is to be renewed; or at the time when improved structures are triggered.
  • Checks in-process of production are regulated in policy. So do we do double checks on delivery from either stock items or order pieces.
  • Double security on material correctness
  • Moreover we pay serious attention to the material compounds, espcially of stainless steel or in norm codes 1.4408 and 1.4404. In-house examination is required on receipt of the bar stock from raw material vendors.
  • Random approval checks are constantly performed in labeling process, or during packaging prior to shipments.
  • ECTFE Abrasive Coating

  • We are able to provide TW couplings MK VK MB VB with ECTFE powder coating. Click to see the PDF files.
  • ECTFE, Ethylene ChloroTriFluoroEthylene, provides excellent chemical resistance in heavy duty corrosion applications.
  • The coating is made 0.6mm strong enough to be used in the transport of aggressive media and chemicals.
