DN 16CF to DN40CF


CF double-sided flanges are designed to be inserted between two flanges of the same size. This provides a simple method for adding thermocouple gauge tubes or upto-air valves to a system with virtually no change in conductance or pumping speed.

All CF double-sided flanges are made of 304ss material. Each assembly requires two gaskets and longer-length bolts.

Caburn-MDC does not recommend stacking more than one double-sided flange in a single assembly.

  • OFE Copper or optional Viton® elastomer gaskets
  • Clearance and blind-tapped bolt holes
  • Conflat® compatible with other manufacturers' knife edge flanges and complies with ISO 3669
