PTFE Lined Reducing Flanges
MVS PTFE Lined Reducing Flanges or Reducing Plates are offered in Wafer style with threaded bolt holes and concentric bores. We manufacture standard reducing flanges which are always in stock with us and can also manufacture special reducing flanges as per customer’s requirements.
We have a custom-made solution for all transitions between the nominal widths. According to the reduction, lined with PTFE or PFA.
Our PTFE Lined Reducing Flange or Plates can be supplied with virgin unpigmented liners or static dissipating (Anti-static) liners to prevent static build up within piping on site. While a full range of sizes are available, non-standard sizes are our specialty.
