‘Step-Up’ PTFE Lined Flange Fitting Design for Corroline+ Hose
Because Corroline+ Hose has better flow rates than some larger bore sizes of Convoluted PTFE hose, it represents a superior alternative when fitted with the larger size flanges in some applications.
It is, however, necessary to also “Step-Up” the PTFE-lined bore, to ensure a diameter match with the mating connector.
This is best achieved using a solid PTFE Adaptor Plate, as shown in the drawing.
