CF Flexible Couplings

CF flange bellows, or often called CF flexible coupling, have a length of flexible tubing with a rotatable CF flange welded on one end and a non-rotatable flange welded to the other end.

The tube is hydroformed and tumble-finished. This flexible coupling is designed to accommodate small axial, angular, and radial misalignment between two mating flanges separated by a gap. The bellows do not need to be supported half-way the tubing.

Bellows are made from 316L or 321 stainless steel. The flanges are made from 304 stainless steel.
