PTFE Lined

Flange Specifications

  • ANSI B16.5 (also ASME B16.5) Class 150# and 300#
  • *DIN PN10, PN16 and PN40
  • JIS 10K
  • Other Pressure Ratings and Flange Specifications are also available.

*DIN PN10, PN16 and PN40 Flanges all have the same dimensions, and so are fully interchangeable

Maximum Pressure Ratings for Flange Fittings

  • ANSI 150# = 16 Bar (230 psi), ANSI 300# = 41.4 Bar (600 psi)
  • DIN PN10 = 10 Bar (145 psi), DIN PN16 = 16 Bar (230 psi)
  • DIN PN40 = 40 Bar (580 psi)

End Fitting Materials

  • Flanges in Grade 304 SS
  • Flange Retainers in Grade 316L SS
  • Ferrules, most in Grade 304 SS, some sizes in Grade 316 SS

Alternative Options for Flange Component only

  • Zinc Plated Carbon Steel

‘Step-Up’ PTFE Lined Flange Fitting Design for Bioflex Ultra Hose

Because Bioflex Ultra 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.
